Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'GM' against the official datasheet to confirm package type and tape/reel specifications. Confirm end-of-life status or obsolescence notices prior to design-in, as availability may be limited. Ensure the selected variant matches the required output format and frequency constraints for the target application.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when low-jitter multiplication is required for dual-output clocks up to 808 MHz. Verify that the input signal meets the specified frequency range of up to 710 MHz. Consider the 251 mA operating current and 36-QFN thermal requirements during PCB layout. Ensure compatibility with the desired output logic levels (CML, LVCMOS, LVDS, or LVPECL).
