Clock distribution buffer for mixed-signal backplanes
The LTC6957IDD-2#TRPBF from Analog Devices is a 1:2 fanout buffer that takes a single clock input in CML, CMOS, LVDS, or LVPECL format and delivers two LVDS outputs. It handles frequencies up to 300 MHz. The supply rail is 3.15 V to 3.45 V. The industrial temperature range is -40°C to 85°C.
Lifecycle and sourcing reality
This part is marked Active on the lifecycle record — no NRND or LTB flags. It's an Analog Devices current-production item, so no forced redesign or last-time-buy scramble. The -2 suffix denotes LVDS output; the -1 variant (LTC6957IDD-1#TRPBF) outputs LVPECL instead, which matters if your downstream receiver expects a different logic swing. For production, the #TRPBF suffix is the standard tape-and-reel option.
