Product details

Clock distribution buffer for mixed-signal backplanes

It handles frequencies up to 300 MHz.

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.

Frequently asked questions

Is LTC6957IDD-2#TRPBF obsolete or still active?

This part is Active per the lifecycle record — it is a current-production item from Analog Devices. There is no NRND or last-time-buy notice, so it remains suitable for new designs.

What are the input and output logic types for LTC6957IDD-2#TRPBF?

The input accepts CML, CMOS, LVDS, or LVPECL signals. The output is LVDS. Both input and output are fully differential.

What is the maximum frequency of LTC6957IDD-2#TRPBF?

The maximum frequency is 300 MHz. That covers gigabit Ethernet reference clocks, FPGA fabric distribution, and ADC/DAC sampling clocks in most industrial systems.

Does LTC6957IDD-2#TRPBF have a direct replacement or equivalent part?

The closest functional equivalent is the LTC6957IDD-2#PBF — same die and LVDS output, but shipped in a tube instead of tape-and-reel. If you need LVPECL output instead of LVDS, the LTC6957IDD-1#TRPBF is the pin-compatible variant. For an extended temperature range, the LTC6957IMS-2#PBF offers the same LVDS output in an MSOP package with the same 300 MHz limit.
