serial JESD204A interface
Rev. 7 — 9 June 2011
Product data sheet
1. General description
The ADC1213D is a dual-channel 12-bit Analog-to-Digital Converter (ADC) optimized for
high dynamic performance and low power at sample rates up to 125 Msps. Pipelined
architecture and output error correction ensure the ADC1213D is accurate enough to
guarantee zero missing codes over the entire operating range. Supplied from a 3 V
source for analog and a 1.8 V source for the output driver, it embeds two serial outputs.
Each lane is differential and complies with the JESD204A standard. An integrated Serial
Peripheral Interface (SPI) allows the user to easily configure the ADC. A set of IC
configurations is also available via the binary level control pins taken, which are used at
power-up. The device also includes a programmable full-scale SPI to allow flexible input
voltage range of 1 V to 2 V (peak-to-peak).
Excellent dynamic performance is maintained from the baseband to input frequencies of
170 MHz or more, making the ADC1213D ideal for use in communications, imaging, and
medical applications.

11. Application information
11.1 Analog inputs
11.1.1 Input stage description
The analog input of the ADC1213D supports a differential or a single-ended input drive.
Optimal performance is achieved using differential inputs with the common-mode input
voltage (VI(cm)) on pins INxP and INxM set to 0.5VDDA
.
The full-scale analog input voltage range is configurable between 1 V (p-p) and 2 V (p-p)
via a programmable internal reference (see Section 11.2 and Table 21).
Figure 6 shows the equivalent circuit of the sample-and-hold input stage, including
ElectroStatic Discharge (ESD) protection and circuit and package parasitics.

Fig 6. Input sampling circuit
The sample phase occurs when the internal clock (derived from the clock signal on pin
CLKP/CLKM) is HIGH. The voltage is then held on the sampling capacitors. When the
clock signal goes LOW, the stage enters the hold phase and the voltage information is
transmitted to the ADC core.
11.1.2 Anti-kickback circuitry
Anti-kickback circuitry (RC filter in Figure 7) is needed to counteract the effects of a
charge injection generated by the sampling capacitance.
The RC filter is also used to filter noise from the signal before it reaches the sampling
stage. The value of the capacitor should be chosen to maximize noise attenuation without
degrading the settling time excessively.

11.2 System reference and power management
11.2.1 Internal/external reference
The ADC1213D has a stable and accurate built-in internal reference voltage to adjust the
ADC full-scale. This reference voltage can be set internally via SPI or with pin VREF and
SENSE (see Figure 11 to Figure 14), in 1 dB steps between 0 dB and 6 dB, via SPI
control bits INTREF[2:0] (when bit INTREF_EN = logic 1; see Table 21). The equivalent
reference circuit is shown in Figure 10. An external reference is also possible by providing
a voltage on pin VREF as described in Figure 13.

11.2.3 Common-mode output voltage (VO(cm)
)
An 0.1 F filter capacitor should be connected between the pins VCMA and VCMB and
ground to ensure a low-noise common-mode output voltage. When AC-coupled, these
pins can be used to set the common-mode reference for the analog inputs, for instance
via a transformer middle point.

(pins INAM, INBM, INAP, and INBP) must be between 0.9 V and 2 V for optimal
performance.

Single-ended or differential clock inputs can be selected via the SPI (see Table 20). If
single-ended is selected, the input pin (CLKM or CLKP) is selected via control bit
SE_SEL.
If single-ended is implemented without setting bit SE_SEL accordingly, the unused pin
should be connected to ground via a capacitor.
11.3.3 Clock input divider
The ADC1413D contains an input clock divider that divides the incoming clock by a factor
of 2 (when bit CLKDIV2_SEL = logic 1; see Table 20). This feature allows the user to
deliver a higher clock frequency with better jitter performance, leading to a better SNR
result once acquisition has been performed.
11.3.4 Duty cycle stabilizer
The duty cycle stabilizer can improve the overall performance of the ADC by
compensating the input clock signal duty cycle. When the duty cycle stabilizer is active
(bit DCS_EN = logic 1; see Table 20), the circuit can handle signals with duty cycles of
between 30 % and 70 % (typical). When the duty cycle stabilizer is disabled
(DCS_EN = logic 0), the input clock signal should have a duty cycle of between 45 % and
55 %.

11.6 Serial Peripheral Interface (SPI)
11.6.1 Register description
The ADC1213D serial interface is a synchronous serial communications port allowing for
easy interfacing with many industry microprocessors. It provides access to the registers
that control the operation of the chip in both read and write modes.
This interface is configured as a 3-wire type (SDIO as bidirectional pin).
SCLK acts as the serial clock, and CS acts as the serial chip select.
Each read/write operation is sequenced by the CS signal and enabled by a LOW level to

Dual 12-bit ADC; serial JESD204A interface
The steps for a data transfer:
1. The falling edge on pin CS in combination with a rising edge on pin SCLK determine
the start of communications.
2. The first phase is the transfer of the 2-byte instruction.
3. The second phase is the transfer of the data which can vary in length but is always be
a multiple of 8 bits. The MSB is always sent first (for instruction and data bytes)
4. A rising edge on pin CS indicates the end of data transmission.

11.6.2 Channel control
The two ADC channels can be configured at the same time or separately. By using the
register “Channel index”, the user can choose which ADC channel receives the next
SPI-instruction. By default the channel A and B receives the same instructions in write
mode. In read mode only A is active.
