Overview

The on-chip DSP is designed to run a suite

The CX20709 is one of Conexant's Audio/

of Voice Processing Algorithms and Audio

Voice DSP CODEC family solutions with

Post Processing Effects offered by

highly integrated hardware DSP, CODEC,

Class-D amplifier, USB, I²S, S/PDIF, and

Conexant. The device features Conexant's

I²C interfaces. The solution features a suite

applications, such as PC Docking System/

Sound-Bar, Portable Multimedia/Navigation

Devices, Smart Home Intercom System,

Media IP Phone, and Unified

The CX20709 operates at supply voltages

down to 3.3 V for analog and 1.8 V for the

management scheme can be configured to

achieve <7.55 mW in sleep mode.

The CX20709 offers multiple digital data

and control I/O for flexible peripheral or

MCU/ MPU connectivity. The device

features one 4-wire and one 5-wire digital

audio interface, which can be mixed or

multiplexed to support bi-directional I²S,

PCM, and S/PDIF. The device can be

controlled and configured by both read and

write capability through I²C and SPI. The

device features a USB 2.0 Compliant Audio

Class interface (full-speed for data and

control) and a UART interface for the

external MCU/MPU interface.

Applications

PC Speakers System

LCD Display/SoundBar

Home Automation/Intercom

PND/PMP

Telepresence/Unified Communication

Device

Embedded Applications

The device integrates three high-

performance 102 dB SNR, 24-bit DACs for

2.1CH speaker output, capless headphone

output, and single-ended/differential line-

output. The analog input paths feature four

high performance, 24-bit ADC supporting up

to four microphones or three stereo Line-

Inputs. Different audio sampling rates

ranging from 8 kHz to 96 kHz are generated

directly from the master clock without the

need for external PLL. The power-efficient

integrated Class-D stereo amplifier operates

at 5 V or 3.3 V with an optional maximum

power of 2.8 W at a 4 Ω load. For intercom

application, the mono line-out supports

600 Ω drivers, which can drive the isolation

transformer directly without an external

operational amplifier.
