PNX0161 personal audio IC

Rev. 01 — 17 January 2008

Product data sheet

1. Introduction

The Nexperia PNX0161 is an integrated IC that serves as USB audio and HID class

device for a USB headset.

2. General description

Recent development in mobile phones is to have the phone equipped with a

USB micro A plug as a single plug for charging and connection to all enhancements (like a

headset, but also for other enhancements like GPS accessories etc.)

The PNX0161 is based on an ARM7TDMI CPU core with data/instruction cache of 8 kB

and USB 2.0 FS device interface.

3. Features

3.1 General features

I Enables one chip solution for USB headset.

I Requires very low power.

I Supports FM radio input including low-power audio bypass mode.

I Is available in a small footprint package TFBGA88 of 7 × 7 sq. mm with 0.5 mm pitch.

3.2 Hardware features

I ARM7TDMI processor core with 8 kB data/instruction cache.

I Embedded SRAM, 32 kB.

I Embedded ROM memory for storing the boot code, 32 kB.

I Embedded ﬂash memory for storing the program code, 256 kB (second production

version will be ROM based).

I Integrated USB 2.0 full-speed device interface.

I Intelligent conﬁguration power management.

I Embedded high-efﬁciency power supply unit powered from a USB supply.

I Supports power optimization by optimizing supply voltages.

I Embedded DMA controller.

I Digital interfaces:

N Integrated stereo ADC with programmable ampliﬁer (microphone, line input and

tuner input).

N Integrated IIS input and output interfaces (conﬁgurable for master/slave options).

N Integrated fast UART with DMA support.

N Integrated master/slave I²C interface.

I Analog interfaces:

N Integrated stereo ADC with programmable ampliﬁer (microphone, line input and

tuner input).

N Microphone bias block.

N Integrated stereo DAC with Class-AB headphone ampliﬁer for high quality audio

with increased driving capabilities and for use in tuner applications.

N The integrated ADC and DAC both have a 24 bits data path.

I Two integrated general purpose timers.

I Integrated watchdog timer.

I Low-power tuner mode with direct connection between tuner input and Class-AB

headphone ampliﬁer with analog volume control.

I JTAG interface with boundary scan and ARM debug access.

3.3 Software features

This section lists the software features that the PNX0161 is capable of performing.

I Playback: playback by the headphones of a received USB audio stream from the

USB host via the DAC.

I Recording: audio stream converted by the ADC from the microphone is sent via the

USB audio stream to the USB host.

I Phone call: in addition to the ﬁrst case, simultaneously returning a USB audio stream

that is converted by the ADC from the microphone. The microphone is mixed to the

headphone stream, known as side-tone mixing.

I Tuner listening: the FM tuner audio stream is sent to the headphones. No stream is

sent or received via USB.

I Tuner recording: the FM tuner audio stream is sent to the headphones. In addition the

FM tuner stream is streamed to the phone via USB.

I USB HID class for FM tuner RDS info.

I USB device ﬁrmware upgrade.

I Intelligent power management software.

I Audio postprocessing features like volume control.

3.4 Software features on request

This section lists the software features that the PNX0161 is capable of performing.

I Audio source selection between line-in and USB audio in for playback path, by toggling

GPIO pin.

I Support for stereo recording from analog and I²S inputs at sample rates other than

48 kHz.

I Support for stereo playback from USB audio, I²S and analog inputs at sample rates

other than 48 kHz.

I Option for a “direct analog link” for playback applications where only volume control is

performed in the PNX0161. The “direct analog link” provides a full analog audio path

through the PNX0161 from the analog stereo line input to the low output impedance

buffer output through an analog volume control block. When the option is not selected,

the analog stereo input is converted to the digital domain by the on-chip ADC. Audio

postprocessing is performed in the digital domain. The processed signals are then

converted back to analog by the on-chip DAC and fed to the analog outputs through

the low impedance output buffer.

I Digital EQ for loudspeaker characteristics compensation.

I For audio rendering applications: digital bass boost, treble expander, stereo widening,

FM radio acoustical performance improvement and other NXP software LifeVibes

music algorithms.

I For applications as USB (mobile)-phones hands-free teleconference stations:

Full duplex acoustic echo cancellation, intelligibility improvement and other NXP

software LifeVibes voice algorithms.
