CS5364

Description

The CS5364 is a complete 4-channel analog-to-digital converter for digital audio systems. It performs sampling, an-

alog-to-digital conversion, and anti-alias filtering, generating 24-bit values for all 4-channel inputs in serial form at

sample rates up to 216 kHz per channel.

The CS5364 uses a 5th-order, multi-bit delta sigma modulator followed by low latency digital filtering and decima-

tion, which removes the need for an external anti-aliasing filter. The ADC uses a differential input architecture which

provides excellent noise rejection.

Dedicated level translators for the Serial Port and Control Port allow seamless interfacing between the CS5364 and

other devices operating over a wide range of logic levels. In addition, an on-chip oscillator driver provides clocking

flexibility and simplifies design.

The CS5364 is the industry’s first audio A/D to support a high-speed TDM interface which provides a serial output

of 4 channels of audio data with sample rates up to 216 kHz within a single data stream. It further reduces layout

complexity and relieves input/output constraints in digital signal processors.

The CS5364 is available in a 48-pin LQFP package in both Commercial (-40°C to 85°C) and Automotive grades

(-40°C to +105°C). The CDB5364 Customer Demonstration board is also available for device evaluation and

implementation suggestions. Please see “Ordering Information” on page 41 for complete ordering information.

The CS5364 is ideal for high-end and pro-audio systems requiring unrivaled sound quality, transparent conversion,

wide dynamic range and negligible distortion, such as A/V receivers, digital mixing consoles, multi-channel record-

ers, outboard converters, digital effect processors, and automotive audio systems.
