ADSP-21362YSWZ-2AA

Digital Signal Processor Dsp Overview

The ADSP-21362YSWZ-2AA is a high-performance 32-bit/40-bit floating-point digital signal processor from Analog Devices, belonging to the SHARC family. It features a single-instruction, multiple-data (SIMD) computational architecture with two processing elements (PEX and PEY). The device integrates 3M bits of on-chip SRAM and 4M bits of mask-programmable ROM. Key audio-centric peripherals include an S/PDIF transceiver, eight channels of asynchronous sample rate converters (SRC), and a Digital Applications Interface (DAI). The core operates at frequencies up to 333 MHz, delivering significant performance for automotive audio applications.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix YSWZ-2AA against the manufacturer's current datasheet to confirm package type (LQFP_EP) and temperature range. Ensure compatibility with development tools such as the ADZS-2136x EZ-KIT Lite. Check for RoHS compliance status in the latest product specifications before procurement.

Digital Signal Processor Dsp Selection Notes

Select the ADSP-21362 model specifically for its inclusion of the DTCP cipher and S/PDIF transceiver, which are absent in other family members like the ADSP-21363. Consider the 3M bit SRAM capacity for buffer requirements. Ensure the system design supports the required power supply voltages and clock configurations via the internal PLL.

Digital Signal Processor Dsp Part Context

This component is part of the ADSP-2136x family, which shares source code compatibility with previous SHARC processors like the ADSP-2126x and ADSP-2116x. The family utilizes Super Harvard Architecture to eliminate I/O bottlenecks. The ADSP-21362 variant is distinct within this group due to its specific combination of audio security and interface features.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21363, ADSP-21364, ADSP-21365, and ADSP-21366 are pin-compatible alternatives within the same family. However, they differ in peripheral availability; for instance, the ADSP-21363 lacks S/PDIF and SRC, while the ADSP-21365 includes DTCP but may have different audio decoder ROM content. Verify peripheral requirements before substitution.
