Procurement Notes

Verify the specific suffix 'LFT' or 'LF' against the manufacturer's current datasheet to confirm lead-free status and RoHS compliance, as packaging variants may exist. Confirm surface-mount availability and check for end-of-life notices or last-time-buy dates, as this component series has seen discontinuation events in related part numbers. Ensure the 48-VFQFPN package footprint matches the design requirements.

Selection Notes

Select this component when designing for UMPC architectures requiring a dedicated main clock source with low power consumption. Ensure the system can accommodate the 1.425V to 3.465V supply range and that the 166.67MHz maximum frequency meets the CPU and peripheral timing requirements. Verify compatibility with the required crystal oscillator input specifications and thermal management for the -40°C to +85°C operating range.

Part Context

This part belongs to the 9UMS9633 series of clock generators originally developed by Integrated Device Technology (IDT), which was later acquired by Renesas Electronics Corporation. The series is optimized for mobile PC applications, providing multiple differential outputs to drive CPUs, memory, and other peripherals with low jitter and power efficiency.

Replacement Considerations

Check for direct pin-compatible replacements within the Renesas 9UMS9633 family, such as the 9UMS9633BKLFT. Verify electrical parameters including frequency, voltage, and package dimensions before substitution.
