Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

The ICS661GILFT is listed with an Obsolete part status. Verification of current availability requires checking distributor stock levels directly, as standard manufacturing supply may be discontinued. RoHS compliance status is marked as non-compliant in available records. Confirm end-of-life documentation and last-time-buy dates through official Renesas channels before design finalization.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component only if the application specifically requires a 73.728MHz fixed frequency output with a 2:2 ratio. Ensure the system power supply remains stable between 3V and 3.6V. The 16-TSSOP package dimensions must fit the PCB footprint constraints. Verify that the non-RoHS status aligns with environmental regulations applicable to the target deployment region.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the ICS661 family of clock generators. The suffix 'GI' typically denotes the industrial temperature range (-40°C to 85°C) and TSSOP package, while 'LFT' indicates lead-free termination. It is distinct from buffer or driver variants like the 8545 series which offer higher frequencies and different pin counts.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

As the part is obsolete, direct substitutes are not explicitly confirmed in public data. Designers should consult Renesas for recommended cross-references or newer generations of clock synthesizers that match the 73.728MHz requirement and 16-TSSOP form factor.
