Product details

Clock buffer selection for multi-standard inputs

The LTC6957IDD-4#PBF is a single-channel fanout buffer that accepts CML, CMOS, LVDS, or LVPECL inputs and delivers a single-ended CMOS output at up to 300 MHz. The 1:2 fanout ratio means one input drives two output copies, useful for splitting a clock to two loads without adding a separate distribution IC.

Supply rail and temperature range

The buffer operates from a 3.15V to 3.45V supply — a 3.3V rail with ±5% regulation is fine, but a rail with high ripple or droop under load may push the buffer out of its specified range.

Active production and sourcing posture

Analog Devices lists the LTC6957IDD-4#PBF as Active in production. Sourced per RFQ against BOM quantity — current pricing and lead time confirmed at quote time.

Frequently asked questions

Will LTC6957IDD-4#PBF drop into a board designed for LTC6957IDD-3#PBF without rewiring?

Both parts share the same package (12-DFN 3×3 mm), supply voltage range, and pinout — the -3 suffix outputs CMOS as well. The -4 variant is functionally identical for a CMOS-output design; no board respin is needed. Confirm the input signal type (CML, CMOS, LVDS, LVPECL) matches your source.
