Digital Signal Processor Dsp Procurement Notes

Verify the suffix 'ZDK' corresponds to the 548-pin BGA package with a 0.8-mm ball pitch as specified in the datasheet. Confirm that the 'A' grade indicates a 1.4-V internal core voltage requirement. Ensure compatibility with existing board designs regarding the specific pinout and power supply configurations defined for this variant.

Digital Signal Processor Dsp Selection Notes

Select the TMS320DM642AZDK7 when high-performance video processing is required alongside network connectivity via the integrated EMAC. The ZDK suffix denotes the 0.8-mm pitch package, which differs from the 1.0-mm pitch GNZ/ZNZ variants. Ensure the design supports the 1.4-V core voltage and 3.3-V I/O levels associated with the A-graded silicon.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C6000 DSP platform, specifically the DM64x series optimized for digital media. It is code-compatible with other C64x devices but adds specialized peripherals for video and imaging. The ZDK package variant is distinct within the family due to its specific physical dimensions and ball pitch requirements.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements must match the 548-pin BGA package with a 0.8-mm ball pitch. Other DM642 variants such as the ZNZ or GNZ suffixes share functional compatibility but differ in package pitch and may require mechanical redesign.
