Application Specific Clock/Timing Procurement Notes

Verify the specific suffix 'BHLF' against official Renesas documentation, as primary sources predominantly reference the 'AHLF' variant. Confirm moisture sensitivity level and lead-free status via the current datasheet. Check for product discontinuance notices or PCNs affecting availability. Ensure the 52-CABGA package dimensions match the design requirements.

Application Specific Clock/Timing Selection Notes

Select this component when designing DDR2 memory subsystems requiring low power consumption and precise clock alignment. Verify that the 1.7V to 1.9V supply voltage aligns with the target platform's power rails. Ensure the 410 MHz maximum frequency meets the memory bus speed requirements. Confirm compatibility with SSTL-18 termination schemes.

Application Specific Clock/Timing Part Context

This part belongs to the Renesas 97U series of specialized clock drivers. It is functionally related to variants such as the 97U877AHLF and ICS97ULP877AHT. These components are engineered for high-performance computing and server applications where low jitter and power efficiency are critical for memory stability.

Application Specific Clock/Timing Replacement Considerations

The 97U877AHLF is a documented variant within the same family. Verify pinout and electrical specifications before substitution. Cross-reference with ICS97ULP877AHT for functional equivalence in DDR2 designs.
