Signal conditioning for high-speed differential links
The Texas Instruments SN65LVP20DRFT is a single-channel differential buffer and re-driver that accepts a differential input and delivers an LVPECL output. It is designed to regenerate and retime signals in LVDS applications, extending the reach of high-speed serial links on backplanes, cables, or long PCB traces. The part operates from a 2.375 V to 3.6 V supply, drawing 35 mA, and is rated over the industrial temperature range of -40°C to 85°C.
4 Gbps data rate and 30 ns delay — what they mean for the link
The 4 Gbps maximum data rate covers common serial standards such as Gigabit Ethernet, SATA, PCIe Gen 1, and LVDS video links. The 30 ns propagation delay adds to the total link latency; in closed-loop or deterministic systems, budget that delay into the timing closure analysis. For most point-to-point or multi-drop LVDS buses, the delay is acceptable and the signal conditioning benefit outweighs the added latency.
Lifecycle and sourcing
It is ROHS3 compliant. No last-time-buy or obsolescence notice is in effect, making it suitable for both new designs and ongoing production BOMs.
