Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify current availability status as the product may be subject to limited supply or discontinuation. Confirm RoHS compliance details through official datasheets. Check for Product Change Notifications (PCN) regarding manufacturing process updates. Ensure compatibility with existing system voltage levels (1.8V/2.5V/3.3V). Validate that the specific suffix 'B' aligns with required configuration options.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when design flexibility for multiple output frequencies is required within a low-power constraint. The in-system programmability allows for post-manufacturing adjustments via I2C. Consider the 350 MHz maximum frequency limit against system clock requirements. Verify that the 24-lead VFQFPN package fits the PCB layout constraints. Ensure support for the desired output types (LVPECL/LVDS/HCSL vs LVCMOS) matches the load requirements.
