Application Specific Clock/Timing Procurement Notes

This component is listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of lifecycle status and alternative sourcing options is required before procurement planning.

Application Specific Clock/Timing Selection Notes

Select this part for systems requiring a high number of synchronized clock outputs from a single source. Ensure the design accommodates the 48-pin TSSOP footprint and the 350 mA current consumption. Verify compatibility with the specific chipset's clock requirements, particularly regarding the 66 MHz maximum output frequency.

Application Specific Clock/Timing Part Context

The 952906 series belongs to the Timing Control Hub (TCH) family, incorporating serially programmable I2C interfaces for adjusting frequency, divider ratios, and output characteristics. This specific model is optimized for PC motherboard architectures, providing essential clock signals for CPU and memory subsystems.

Application Specific Clock/Timing Replacement Considerations

Check for direct pin-compatible substitutes within the same TCH family or newer generations from Renesas. Consider generic programmable clock generators if specific TCH features are not critical.
