CX20672 HD Audio Codec with 2W Class-D, Capless HP,

Retasking, and SPDIF Out

Overview

Features

Conexant's CX20672 is a low-power, 102 dB SNR HD Audio codec with integrated 2-

WRMS stereo Class-D using Spread Spectrum dispersion technology to prevent EMI.

Two independent pairs of DACs and three independent pairs of ADCs support multi-

Streaming and Real Time Communications applications. The audio fidelity of the device

exceeds Microsoft Premium Logo requirements.

2 pairs of independent DACs and 3

pairs of independent ADCs

Sampling rates include 16-bit, 44.1

kHz to 24-bit, 192 kHz for DACs, and

from 16-bit, 44.1 kHz to 24-bit; 96 kHz

for ADCs.

Integrated 2 WRMS (per channel)

Class-D stereo speaker amplifier

Capless headphone eliminates BOM

Two retaskable ports

A ProCoustic capless headphone driver delivers 31 mW per channel into 32 Ω loads and

eliminates external DC blocking capacitors. Two retaskable ports are available allowing

Microphone/Line in and Microphone/Line In/Line Out retasking. All output ports feature

PopShield technology that eliminates pops and clicks.

Stereo Digital Microphone interface

Integrated boost for all microphones

One independent SPDIF output

Integrated regulators maximize

performance

The codec features a stereo digital microphone interface that includes a hardware DC-

level filter to remove DC offset and provides the clock output. One independent SPDIF

output is available supporting sample rates up to 96 kHz, 16-24-bit resolution. Multiple

GPIO's are provided, including speaker mute and EAPD functions.

Record Security Control

Integrated headphone limiter (GS

Mark)

Integrated 5 V to 3.3 V and 3.3 V to 1.8 V Low Dropout (LDO) regulators guarantee high

performance analog audio and clean power to internal digital blocks. Conexant's D-Flex

power management allows the system to exceed the power savings specified in the Intel

ECR 15B. The internal Wake-on-BEEP logic resumes the analog paths for the PC BEEP

to the output ports.
