ALC262 Series
Datasheet
1. General Description
The ALC262 series are 4-Channel DAC and 6-Channel ADC High Definition Audio Codecs with UAA
(Universal Audio Architecture). Featuring two 24-bit stereo DACs and three 24-bit stereo ADCs (the
ALC262, ALC262-VB and ALC262-VC support 20-bit ADC format, the ALC262-VD supports 24-bit
ADC format), they are designed for high-performance multimedia desktop and laptop systems. The
ALC262 series incorporates proprietary converter technology to achieve over 100dB Signal-to-Noise
ratio playback quality.
The ALC series meets the current WLP3.10 (Windows® Logo Program) requirements, and the
ALC262-VD (D version) meets future WLP requirements that become effective from 01 June 2008,
bringing PC sound quality closer to consumer electronic devices.
The ALC262 series provide 4 channels of DAC, supporting stereo sound playback on the rear panel and
independent stereo sound output on the front panel simultaneously (multiple streaming), along with
flexible mixing, mute, and fine gain control functions to provide a complete integrated audio solution.
The ALC262 series also integrates three stereo ADCs that can support a microphone array with Acoustic
Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technology simultaneously,
significantly improving sound quality for PC VoIP applications. With this unique feature (3 stereo ADCs),
the ALC262 can provide high-quality audio using S/PDIF to output analog data, or for multiple-source
recording applications.
All analog IO are input and output capable and can be re-tasked according to user’s definitions.
Headphone amplifiers are also integrated at analog output ports A, B, C, D, E, and F. The ALC262 series
supports 16/20/24 S/PDIF input and output to offer easy connection of PCs to high quality consumer
electronic products such as digital decoders and speakers.
The ALC262 series supports host/soft audio from the Intel ICH chipset, and also from any other HDA
compatible audio controller. With EAX/Direct Sound 3D/I3DL2/A3D compatibility, and excellent
software utilities like Karaoke mode, environment emulation, software equalizer, HRTF 3D positional
audio, and optional Dolby®, SRS®, Fortemedia® and Waves® audio technology the ALC262 provides an
excellent entertainment package and game experience for PC users.

Two functions are added in the ALC262 C version:
• Addition of a digital microphone interface. The ALC262 C version supports most digital microphones
currently available. With digital microphone implementation, a notebook computer can achieve better
voice input quality without noise interference caused by geometric PCB layout and radio frequency
devices
• The ALC262 C supports scalable I/O voltage (1.5V to 3.3V) on an HDA link, which will be a
requirement in future chipsets designed for low voltage operation.
The ALC262 D supports a secondary S/PDIF output converter and a dedicated output pin (S/PDIF-OUT2)
to a HDMI transmitter, and all ADCs support up to192K sample rate and 24-bit PCM format. The
ALC262 D version conforms to Intel’s Audio Codec low power state white paper and is ECR compliant,
with improved frequency response at a 44.1kHz sampling rate, and THD+N measured at -1dB full scale
in compliance with future WLP requirements that become effective from 01 June 2008.
Note: ALC262 version differences are listed in section 12 Ordering Information, page 78.

7. High Definition Audio Link Protocol
7.1. Link Signals
The High Definition Audio (HDA) Link is the digital serial interface that connects the HDA codecs to the
HDA Controller. The HDA link protocol is controller synchronous, based on a 24.0MHz BIT-CLK sent
by the HDA controller. The input and output streams, including command and PCM data, are isochronous
with a 48kHz frame rate. Figure 8 shows the basic concept of the HDA link protocol.

BCLK
SYNC
24.0MHz of bit clock sourced from the HDA controller and connecting to all codecs.
48kHz of signal is used to synchronize input and output streams on the link. It is sourced from the HDA
controller and connects to all codecs.
SDO
Serial data output signal driven by the HDA controller to all codecs. Commands and data streams are
carried on SDO. The data rate is double pumped; the controller drives data onto the SDO, the codec
samples data present on SDO with respect to each edge of BCLK. The HDA controller must support at
least one SDO. To extend outbound bandwidth, multiple SDOs may be supported.
SDI
Serial data input signal driven by the codec. It is point-to-point serial data from the codec to the HDA
controller. The controller must support at least one SDI, and up to a maximum of 15 SDI’s can be
supported. SDI is driven by the codec at each rising edge of BCLK, and sampled by the controller at each
rising edge of BCLK. SDI can be driven by the controller to initialize the codec’s ID.
RST#
Active low reset signal. Asserted to reset the codec to default power on state. RST# is sourced from the
HDA controller and connects to all codecs.

Signaling Topology
The HDA controller supports two SDOs for the outbound stream, up to 15 SDIs for the inbound stream.
RST#, BCLK, SYNC, SDO0, and SDO1 are driven by controller to codecs. Each codec drives its own
point-to-point SDI signal(s) to the controller.
Figure 10 shows the possible connections between the HDA controller and codecs:
• Codec 0 is a basic connection. There is one single SDO and one single SDI for normal transmission
• Codec 1 has two SDOs for doubled outbound rate, a single SDI for normal inbound rate
• Codec 3 supports a single SDO for normal outbound rate, and two SDIs for doubled inbound rate
• Codec N has two SDOs and multiple SDIs
The multiple SDOs and multiple SDIs are used to expand the transmission rate between controller and
codecs. Section 7.2 Frame Composition, page 18, describes the detailed outbound and inbound stream
compositions for single and multiple SDOs/SDIs.
The connections shown in Figure 10 can be implemented concurrently in an HDA system. The ALC262
is designed to receive a single SDO stream.

7.2. Frame Composition
7.2.1.
Outbound Frame – Single SDO
An outbound frame is composed of one 32-bit command stream and multiple data streams. There are one
or multiple sample blocks in a data stream. Only one sample block exists in a stream if the HDA
controller delivers a 48kHz rate of samples to the codec. Multiple sample blocks in a stream means the
sample rate is a multiple of 48kHz. This means there should be 2 blocks in the same stream to carry
96kHz samples (Figure 11).
For outbound frames, the stream tag is not in SDO, but in the SYNC signal. A new data stream is started
at the end of the stream tag. The stream tag includes a 4-bit preamble and 4-bit stream ID (Figure 12).
To keep the cadence of converters bound to the same stream, samples for these converters must be placed
in the same block.

7.2.2.
Outbound Frame – Multiple SDO
The HDA controller allows two SDO signals to be used to stripe outbound data, completing transmission
in less time to get more bandwidth. If software determines the target codec supports multiple SDO
capability, it enables the ‘Stripe Control’ bit in the controller’s Output Stream Control Register to initiate
a specific stream (Stream ‘A’ in Figure 13) to be transmitted on multiple SDOs. In this case, the MSB of
stream data is always carried on SDO0, the second bit on SDO1 and so forth.
SDO1 is for transmitting a striped stream. The codec does not support multiple SDOs connected to

To guarantee all codecs can determine their corresponding stream, the command stream is not striped. It
is always transmitted on SDO0, and copied on SDO1.

Inbound Frame – Single SDI
An Inbound Frame – A single SDI is composed of one 36-bit response stream and multiple data streams.
Except for the initialization sequence (turnaround and address frame), SDI is driven by the codec at each
rising edge of BCLK. The controller also samples data at the rising edge of BCLK (Figure 14).
The SDI stream tag is not carried by SYNC, but included in the SDI. A complete SDI data stream
includes one 4-bit stream tag, one 6-bit data length, and n-bit sample blocks. Zeros will be padded if the
total length of the contiguous sample blocks within a given stream is not of integral byte
length (Figure 15).

Inbound Frame – Multiple SDI
A codec can deliver data to the controller on multiple SDIs to achieve higher bandwidth. If an inbound
stream exceeds the data transfer limits of a single SDI, the codec can divide the data onto separate SDI
signals, each of which operate independently, with different stream numbers at the same frame time. This
is similar to having multiple codecs connected to the controller. The controller samples the divided stream
into separate memory with multiple DMA descriptors, then software re-combines the divided data into a
meaningful stream.

Variable Sample Rates
The HDA link is designed for sample rates of 48kHz. Variable rates of sample are delivered in multiple or
sub-multiple rates of 48kHz. Two sample blocks per frame result in a 96kHz delivery rate, one sample
block over two frames results in a 24kHz delivery rate. The HDA specification states that the sample rate
of the outbound stream be synchronized by the controller, not by the codec. Each stream has its own
sample rate, independent of any other stream.
The HDA controller supports 48kHz and 44.1kHz base rates. Table 7, page 22, shows the recommended
sample rates based on multiples or sub-multiples of one of the two base rates.
Rates in sub-multiples (1/n) of 48kHz are interleaving n frames containing no sample blocks. Rates in
multiples (n) of 48kHz contain n sample blocks in a frame. Table 8, page 22, shows the delivery cadence
of variable rates based on 48kHz.
The HDA link is defined to operate at a fixed 48kHz frame rate. To deliver samples in (sub) multiple
rates of 44.1kHz, an appropriate ratio between 44.1kHz and 48kHz must be maintained to avoid
frequency drift. The appropriate ratio between 44.1kHz and 48kHz is 147/160. Meaning 147 sample
blocks are transmitted every 160 frames.

The cadence ‘12-11-11-12-11-11-12-11-11-12-11-11-11- (repeat)’ interleaves 13 frames containing no
sample blocks in every 160 frames. It provides a low long-term frequency drift for 44.1kHz of delivery
rate. Rates in sub-multiples (1/n) of 44.1kHz also follow this cadence and interleave n empty frames.
Rates in multiples (n) of 44.1kHz applying this cadence contain n sample blocks in the non-empty frame
and interleave an empty frame between non-empty frames (Table 9, page 23).

7.3. Reset and Initialization
There are two types of reset within an HDA link:
• Link Reset. Generated by assertion of the RST# signal, all codecs return to their power on state
• Codec Reset. Generated by software directing a command to reset a specific codec back to its default
state
An initialization sequence is requested after any of the following three events:
1. Link Reset
2. Codec Reset
3. Codec changes its power state (For example, hot docking a codec to an HDA system)
7.3.1.
Link Reset
A link reset may be caused by 3 events:
1. The HDA controller asserts RST# for any reason (power up, or PCI reset)
2. Software initiates a link reset via the ‘CRST’ bit in the Global Control Register (GCR) of the HDA
controller
3. Software initiates power management sequences. Figure 17, page 25, shows the ‘Link Reset’ timing
including the ‘Enter’ sequence (n~r) and ‘Exit’ sequence (s~v)
Enter ‘Link Reset’:
n Software writes a 0 to the ‘CRST’ bit in the Global Control Register of the HDA controller to initiate a
link reset
o As the controller completes the current frame, it does not signal the normal 8-bit frame SYNC at the
end of the frame
p The controller drives SYNC and all SDOs to low. Codecs also drive SDIs to low
q The controller asserts the RST# signal to low, and enters the ‘Link Reset’ state
r All link signals driven by controller and codecs should be tri-state by internal pull low resistors

Exit from ‘Link Reset’:
s If BCLK is re-started for any reason (codec wake-up event, power management, etc.)
t Software is responsible for de-asserting RST# after a minimum of 100µsec BCLK running time (the
100µsec provides time for the codec PLL to stabilize)
u Minimum of 4 BCLK after RST# is de-asserted, the controller starts to signal normal frame SYNC
v When the codec drives its SDI to request an initialization sequence (when the SDI is driven high at the
last bit of frame SYNC, it means the codec requests an initialization sequence)

Codec Reset
A ‘Codec Reset’ is initiated via the Codec RESET command verb. It results in the target codec being
reset to the default state. After the target codec completes its reset operation, an initialization sequence is
requested.
In ALC262 D version, the extend power state of conforming to Intel low power ECR the function reset
could not initialize the register setting. Host SW needs to send ‘two’ function reset consecutively to reset
all settings.

Response Format
There are two types of response from the codec to the controller. Solicited Responses are returned by the
codec in response to a current command verb. The codec will send Solicited Response data in the next
frame, without regard to the Set (Write) or Get (Read) command. The 32-bit Response is interpreted by
software, opaque to the controller.
Unsolicited Responses are sent by the codec independently of software requests. Jack Detection or GPI
status information can be actively delivered to the controller and interpreted by software. The ‘Tag’ in
Bit[31:28] is used to identify unsolicited events. This tag is undefined in the HDA specifications.

ALC262 A/B/C Versions
The ALC262 does not support Wake-Up events when in low power mode. All power management state
changes in widgets are driven by software. Table 14 shows the System Power State Definitions.
In the ALC262, all the widgets include output/input converters support power control. Software may have
various power states depending on system configuration. Table 15 indicates those nodes that support
power management. To simplify power control, software can configure whole codec power states through
the audio function (NID=01h). Output converters (DACs) and input converters (ADCs) have no
individual power control to supply fine-grained power control.

ALC262 D Version
The ALC262 version D is designed to meet Intel’s low-power-state white paper and is ECR HDA-015B
compliant. It meets the five attributes discussed in the white paper:
1. D3 state power < 30mW.
2. Exit latency (D3 to D0 transfer) < 10ms.
3. Audio pop/click suppression during D3 and D0 transition < -65dBV.
4. Supports Jack detection in D3 state.
5. D3 functions with or without the BITCLK
The ALC262-VD minimizes D3 state idle mode power consumption and increases overall battery life in
mobile systems.
In D3 mode, only a power on reset or a ‘double function reset’ resets all ALC262-VD settings, cutting
software configuration time spent entering/leaving D3 state, and reducing latency time for D3 to D0
transitions.
The ALC262-VD supports Wake-Up events in D3 mode, including jack detection and GPIO status
changes. If the HDA-Link was alive (with BCLK), the ALC262-VD Wake-Up response is as normal. If
no BITCLK is present, the ALC262-VD drives the SDI high in order to wake up the system.

10. Application Notes
10.1. Application Circuit
Please contact Realtek for the latest application circuits. To get the best compatibility in hardware design
and software driver, any modification should be confirmed by Realtek. Realtek may upload the latest
application circuits onto our web site (www.realtek.com.tw) without modifying this datasheet.
10.2. Volume Control Via External Variable Resistor
The input range of DCVOL is from GND to AVDD. A 5-bit resolution ADC converts the DC level on the
variable resistor into 32 steps for the Volume knob. DC level changes will be reflected to software to
control the master volume.

10.3. Volume Control Via GPIO0/GPIO1
Detected low pulses generated at GPIO0 and GPIO1 are used to calculate the Up and Down count into 7
bits of volume steps. ‘Mute’ is also sampled to toggle the mute status. Hardware will not adjust volume.
The count value will be reported via unsolicited response to software to control the master volume.

10.4. Digital Microphone Implementation
This section describes the ALC262 digital microphone implementation. There is one Clock output pin
and 1 Data input pin in the ALC262. The ALC262 provides the clock signal to the digital microphone.
When the digital microphone receives the external sound input, it converts the analog signals to digital in
a 1-bit format. The 1-bit data is delivered to the codec though the data input pin. The Digital Filter in the
audio codec converts the 1-bit data stream into Pulse Code Modulation (PCM) data. The PCM data is sent
to the HDA controller through the HDA link.

Track ID: JATR-1076-21 Rev. 1.9
ALC262 Series
Datasheet
The ALC262 supports a two-wire interface for the digital microphone and operates in single channel
(mono type) or stereo channels (stereo) digital microphone mode. One pin is clock output to the digital
microphone, and the other is a serial pin. The default clock output is 2.048MHz.
In Type 1 (Figure 26), the ALC262 uses one data pin to support mono input from digital microphones
with an LMV1024 (L), SPD0205ND (L), or AKU2000 (L).
In Type 2 (Figure 26), the ALC262 uses one data pin to support stereo inputs from digital microphones
with an LMV1024/1026 (L/R), SPD0205ND (L & R), or AKU2000 (L & R).
Figure 26. Digital Microphone Implementation-2
By default the left channel digital microphone data is sampled at the rising edge of clock, and the right
channel data at the falling edge of clock. Figure 27 indicates 20nsec setup time and 5ns hold time are
required to allow the ALC262 to get individual data correctly.
