The CS5368 is a complete 8-channel analog-to digital converter for digital audio systems. It performs sampling, analog-to-digital conversion, and anti-alias filtering, generating 24-bit values for all 8-channel inputs in serial form at sample rates up to 216 kHz per channel. The CS5368 uses a 5th-order, multi-bit delta sigma modulator followed by low latency digital filtering and decimation, 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 CS5368 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 CS5368 is the industry’s first audio A/D to support a high-speed TDM interface which provides a serial output of 8 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.
