1:4 LVDS fanout buffer — what this part does
The Texas Instruments SN65LVDS104PWR is a 1:4 LVDS buffer and multiplexer that takes one differential LVDS input and distributes it to four LVDS outputs. It is used in high-speed signal distribution for clock or data fanout in telecom, industrial backplane, and test equipment where signal integrity over a point-to-point link matters.
400Mbps data rate and 3.1ns delay — timing budget fit
The 400Mbps maximum data rate covers common LVDS serial links for video, ADC data, and backplane interfaces. The 3.1ns propagation delay is the pin-to-pin latency through the buffer; when cascading multiple fanout stages, this delay adds directly to the link timing budget. The 3pF input capacitance keeps the loading on the driving source light, which helps maintain signal rise times at the source.
16-TSSOP footprint and surface-mount assembly
It is surface-mount only, so the PCB layout should follow the standard TSSOP-16 land pattern. The 23mA supply current is modest, so no special thermal management is needed for most designs.
