CS496112-IQZ

Digital Signal Processor Dsp Overview

The CS496112-IQZ is a digital signal processor from the Cirrus Logic CS4961xx family, integrating CobraNet technology with a 32-bit fixed-point DSP core. It provides eight simultaneous channels of serial audio input and output, supporting sample rates up to 96 kHz. The device features selectable network latency options of 1.33, 2.66, or 5.33 ms and includes a high-speed parallel host port interface for system control. Designed for professional and commercial networked-audio applications, it allows audio processing from local inputs or the network. The component is housed in a 144-pin LQFP package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'IQZ' against official documentation to confirm temperature range and packaging details, as datasheets may list generic family variants. Confirm current production status and lead times directly with authorized distributors, as availability for this specific part number may vary.

Digital Signal Processor Dsp Selection Notes

Select the CS496112-IQZ when eight bidirectional audio channels are required within a CobraNet-enabled system. Ensure the design supports the necessary 3.3V I/O and 1.8V core voltage levels. Consider the 144-pin LQFP footprint for PCB layout constraints and verify that the 120 MIPS processing power meets the complexity of the intended DSP algorithms.

Digital Signal Processor Dsp Part Context

This component belongs to the CS4961xx series, which also includes the CS496102 (2-channel) and CS496122 (16-channel). All members share the same core architecture and CobraNet integration but differ in the number of available serial audio ports. This specific model sits in the middle of the family, offering a balance between channel count and pin count.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include the CS496102-IQZR for reduced channel requirements or the CS496122-IQZR for increased channel capacity. Pin compatibility exists across the family, but firmware and software configuration must be adjusted to match the specific channel count and memory resources of the substitute part.
