Procurement Notes

Verify the specific ordering suffix to confirm the reel packaging configuration, as indicated by the 'AGR' designation. Ensure that the required dual frequencies (128.788 MHz and 156.25 MHz) match the target application specifications before procurement. Confirm compatibility with the 3.3 V supply voltage and LVPECL interface requirements. Check for any moisture sensitivity level restrictions during storage and handling procedures.

Selection Notes

Select this component when dual-frequency generation is necessary within a single package footprint. The Si512 series offers pin-configurability, which simplifies board layout compared to discrete solutions. Consider the LVPECL output format for noise immunity in high-speed environments. Evaluate the 43 mA current draw against system power budgets. The 7x5 mm package size should be assessed against available PCB real estate constraints.

Part Context

This part belongs to the Skyworks Si512 family of pin-configurable oscillators. These devices are engineered to replace multiple discrete components by integrating frequency generation and buffering capabilities. The series supports various output formats and supply voltages, offering designers flexibility in creating customized clock solutions without extensive redesign efforts.

Replacement Considerations

The 512ACA000543AAG is listed as a parameter-equivalent substitute. Verify that the non-reel variant meets all electrical and mechanical requirements. Ensure that the absence of the 'R' suffix does not impact availability or packaging preferences for automated assembly processes.
