Digital Signal Processor Dsp datasheet and documents for CS48DV2A-CQZR

CS48DV2A-CQZR

Digital Signal Processor Dsp Overview

The CS48DV2A-CQZR is a fixed-function audio DSP processor integrating Dolby Volume technology. It supports up to 2.1 channel 32-bit PCM I/O at sample rates of 32kHz, 44.1kHz, and 48kHz. The device features an integrated S/PDIF transmitter and DSD input support. It operates with low-power standby consuming 260µW. Control is managed via SPI/I²C serial ports. The processor utilizes a 512 FFT window with 20-band processing for consistent volume across all content.

Digital Signal Processor Dsp Procurement Notes

Verify the specific revision suffix against current manufacturer documentation. Ordering suffixes may indicate silicon revisions or automotive qualification status. Confirm package availability and lead times directly with authorized distributors as stock levels fluctuate.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring up to 2.1 channel audio processing. For systems needing 5.1 channel support, consider the CS48DV6 variant. Ensure the host microcontroller can interface via SPI or I²C for firmware configuration and parameter adjustment.

Digital Signal Processor Dsp Part Context

This component belongs to the CS48DVx Processor family designed for cost-effective Dolby Volume implementation. It simplifies system design by eliminating the need for external SRAM/SDRAM memory. The device allows firmware downloads from a host microcontroller or external SPI Flash device.

Digital Signal Processor Dsp Replacement Considerations

The CS48DV2B-CQZ is a subsequent silicon revision available from April 2008. The CS48DV6B-CQZ provides equivalent functionality but supports up to 5.1 channels instead of 2.1.
