CS496112-IQZR

Digital Signal Processor Dsp Overview

The CS496112-IQZR is a digital signal processor from the CS4961xx family, integrating CobraNet technology with a 32-bit fixed-point DSP core. It provides eight simultaneous serial audio inputs and outputs, supporting sample rates up to 96 kHz. The device features selectable network latency of 1.33, 2.66, or 5.33 ms and includes 32-bit synchronous serial digital audio I/O. Powered by a 1.80 V core voltage and 3.30 V I/O voltage, it operates within a temperature range of -40°C to 85°C. Packaged in a 144-pin LQFP (20x20 mm), it supports ASI, CobraNet, EBI/EMI, HMI, SSAI, and UART/USART interfaces.

Digital Signal Processor Dsp Procurement Notes

Verify component status as the CS4961xx series is listed as discontinued in distributor records. Confirm availability through authorized channels for legacy support. Ensure compatibility with existing CobraNet infrastructure during integration planning.

Digital Signal Processor Dsp Selection Notes

Select the CS496112-IQZR when eight audio channels are required, distinguishing it from the two-channel CS496102 and sixteen-channel CS496122 variants. Verify that the 144-pin LQFP package fits the PCB layout constraints. Ensure the design accommodates the specified 1.8 V core and 3.3 V I/O power requirements.

Digital Signal Processor Dsp Part Context

This component belongs to the CS4961xx family, which combines Cirrus Logic's CobraNet technology with high-performance DSP capabilities. The family aims to reduce system costs by eliminating separate dedicated audio DSPs. The CS496112 specifically targets applications requiring moderate channel counts compared to the broader family offerings.

Digital Signal Processor Dsp Replacement Considerations

Public confirmed substitute part numbers are not available. Consider evaluating other CobraNet-enabled DSPs from Cirrus Logic or alternative manufacturers if this specific model is unavailable.
