Product details

Clock distribution for mixed-signal boards

The LTC6957IMS-3#TRPBF is a 1:2 fanout buffer that accepts CML, CMOS, LVDS, or LVPECL inputs and delivers a single-ended CMOS output at up to 300 MHz.

Input flexibility, output simplicity

The input accepts four common differential and single-ended standards (CML, CMOS, LVDS, LVPECL), while the output is CMOS only — this is the -3 variant's defining trade-off compared to the -1 version which outputs LVPECL. The single 1:2 fanout is useful for splitting a reference clock to two ASICs or FPGAs without adding skew from separate buffers.

Active production, tape-and-reel delivery

Frequently asked questions

What is the difference between LTC6957IMS-3 and LTC6957IMS-1?

The -3 variant outputs CMOS, while the -1 variant outputs LVPECL. Both accept the same input types (CML, CMOS, LVDS, LVPECL) and share the same 300 MHz maximum frequency and 12-MSOP package.

Is LTC6957IMS-3#TRPBF RoHS compliant?

Yes, it is ROHS3 compliant.
