General Description
The CS4207 is a highly integrated multi-channel low-
power HD Audio Codec featuring 192 kHz DACs,
96 kHz ADCs, 192 kHz S/PDIF Transmitters and Re-
ceiver, Microphone pre-amp and bias voltage, and a
ground centered Headphone driver. Based on multi-bit,
delta-sigma modulation, it allows infinite sample rate
adjustment between 32 kHz and 192 kHz.
The ADC input path allows control of a number of fea-
tures. The microphone input path includes a selectable
programmable-gain pre-amplifier stage and a low-noise
MIC bias voltage supply. A PGA is available for line and
microphone inputs and provides analog gain with soft
ramp and zero cross transitions. The ADC also features
an additional digital volume attenuator with soft ramp
transitions.
The stereo headphone amplifier is powered from a sep-
arate internally generated positive supply, with an
integrated charge pump providing a negative supply.
This allows a ground-centered analog output with a
wide signal swing and eliminates external DC-blocking
capacitors.
The integrated digital audio interface receiver and trans-
mitters utilize a 24-bit, high-performance, monolithic
CMOS stereo asynchronous sample rate converter to
clock align the PCM samples to/from the S/PDIF inter-
faces. Auto detection of non-PCM encoded data
disables the sample rate conversion to preserve bit ac-
curacy of the data.
In addition to its many features, the CS4207 operates
from a low-voltage analog and digital core, making this
part ideal for portable systems that require low power
consumption in a minimal amount of space.
The CS4207 is available in a 48-pin WQFN package in
both Automotive (-40°C to +105°C) and Commercial
(-40°C to +85°C) grades. The CS4207 Customer Dem-
onstration board is also available for device evaluation
and implementation suggestions. Please refer to “Or-
dering Information” on p 147 for complete ordering
information.
