Product details

Device identity and key parametrics

The LTC6957IDD-1#PBF is a 1:2 fanout buffer from Analog Devices, accepting CML, CMOS, LVDS, or LVPECL inputs and delivering LVPECL outputs at up to 300 MHz. Supply voltage is tight at 3.15V to 3.45V, so the 3.3V rail must be clean and within ±4.5% — a standard 3.3V ±5% supply is marginal without post-regulation.

Package and footprint considerations

Supplied in Tube (the #PBF suffix denotes lead-free, ROHS3-compliant finish). For reel quantities, order the LTC6957IDD-1#TRPBF variant.

Lifecycle and supply posture

Sourced to order against your BOM quantity; confirm lead time and pricing via RFQ.

Frequently asked questions

What input signal types does LTC6957IDD-1#PBF accept?

It accepts CML, CMOS, LVDS, or LVPECL inputs — covering the common differential and single-ended clock standards used in high-speed digital systems.

Can LTC6957IDD-1#PBF replace LTC6957IDD-2#PBF?

No — the -1 outputs LVPECL, while the -2 outputs LVDS. They are not pin-compatible replacements; the output logic family must match the downstream receiver.
