GENERAL DESCRIPTION
The CS42L51 is a highly integrated, 24-bit, 96 kHz, low
power stereo CODEC. Based on multi-bit, delta-sigma
modulation, it allows infinite sample rate adjustment be-
tween 4 kHz and 96 kHz. Both the ADC and DAC offer
many features suitable for low power, portable system
applications.
The ADC input path allows independent channel control
of a number of features. An input multiplexer selects be-
tween line-level or microphone level inputs for each
channel. The microphone input path includes a select-
able programmable-gain pre-amplifier stage and a low
noise MIC bias voltage supply. A PGA is available for
line or microphone inputs and provides analog gain with
soft ramp and zero cross transitions. The ADC also fea-
tures a digital volume attenuator with soft ramp
transitions. A programmable ALC and Noise Gate mon-
itor the input signals and adjust the volume levels
appropriately.
The DAC output path includes a digital signal process-
ing engine. Tone Control provides bass and treble
adjustment of four selectable corner frequencies. The
Mixer allows independent volume control for both the
ADC mix and the PCM mix, as well as a master digital
volume control for the analog output. All volume level
changes may be configured to occur on soft ramp and
zero cross transitions. The DAC also includes de-em-
phasis, limiting functions and a beep generator
delivering tones selectable across a range of two full
octaves.
The stereo headphone amplifier is powered from a sep-
arate positive supply and the integrated charge pump
provides a negative supply. This allows a ground-cen-
tered analog output with a wide signal swing and
eliminates external DC-blocking capacitors.
In addition to its many features, the CS42L51 operates
from a low-voltage analog and digital core, making this
CODEC ideal for portable systems that require ex-
tremely low power consumption in a minimal amount of
space.
The CS42L51 is available in a 32-pin QFN package in
both Commercial (-10 to +70° C) and Automotive
grades (-40 to +85° C). The CDB42L51 Customer Dem-
onstration board is also available for device evaluation
and implementation suggestions. Please see “Ordering
Information” on page 85 for complete details.
