SYSTEM FEATURES

GENERAL DESCRIPTION

! 24-bit Converters

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.

! 4 kHz to 96 kHz Sample Rate

! Multi-bit Delta Sigma Architecture

! Low Power Operation

–

Stereo Playback: 12.93 mW @ 1.8 V

Stereo Record and Playback: 20.18 mW @

1.8 V

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.

! Variable Power Supplies

–

1.8 V to 2.5 V Digital & Analog

1.8 V to 3.3 V Interface Logic

! Power Down Management

–

ADC, DAC, CODEC, MIC Pre-Amplifier,

PGA

! Software Mode (I²C & SPI™ Control)

! Hardware Mode (Stand-Alone Control)

! Digital Routing/Mixes:

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.

–

Analog Out = ADC + Digital In

Digital Out = ADC + Digital In

Internal Digital Loopback

Mono Mixes

! Flexible Clocking Options

–

Master or Slave Operation

High-Impedance Digital Output Option (for

easy MUXing between CODEC and Other

Data Sources)

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.

–

Quarter-Speed Mode - (i.e. Allows 8 kHz Fs

while maintaining a flat noise floor up to

16 kHz)

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.

APPLICATIONS

! HDD & Flash-Based Portable Audio Players

! MD Players/Recorders

! PDAs

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 81 for complete details.

! Personal Media Players

! Portable Game Consoles

! Digital Voice Recorders

! Digital Camcorders

! Digital Cameras

! Smart Phones
