Application Specific Clock/Timing Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm pinout and electrical characteristics. Confirm that the 24-TSSOP package matches the target PCB footprint. Ensure the supply voltage range of 3.15V to 3.6V aligns with the system design. Check for moisture sensitivity labeling if long-term storage is anticipated before assembly.

Application Specific Clock/Timing Selection Notes

Select this component when designing systems requiring Direct Rambus Lite compatibility. The dual PLL architecture allows for flexible frequency synthesis. Ensure the application environment stays within the 0°C to 70°C operational temperature range. Verify that the non-differential output configuration meets the noise immunity requirements of the target memory bus.
