4-channel 8 Gbps ReDriver for PCIe/SAS/SATA
The SN75LVPE3410RNQT is a 4-channel differential buffer and ReDriver from Texas Instruments, designed to extend the reach of high-speed serial links. It handles data rates up to 8 Gbps, making it a fit for PCIe Gen3, SAS 3.0, and SATA 6 Gb/s lanes where signal integrity degrades over long traces or through connectors. With a 70 ps typical propagation delay and input capacitance of 1.5 pF, the part adds minimal latency and loading to the bus — important for timing closure on a multi-drop backplane or a riser card where the eye margin is tight.
Signal conditioning and supply
The device integrates input equalization and output de-emphasis, meaning it can compensate for channel loss on the receive side and pre-emphasize the transmit edge to open the eye at the far end. No external conditioning components are needed for most board-to-board or cable runs up to the rated data rate. Supply range is 3 V to 3.6 V, drawing 150 mA typical from a single rail. The 40-WFQFN exposed-pad package (6x4 mm, 40-WQFN) requires a thermal-land pattern on the PCB to pull heat from the die — the exposed pad must be soldered to a ground plane with adequate via stitching for thermal relief. Rated for the commercial temperature range (0°C to 70°C ambient), it suits indoor equipment, server motherboards, storage arrays, and switch line cards — not extended-temperature or outdoor deployment without thermal analysis.
Lifecycle and sourcing
Sourced through authorized and independent distribution channels. No pin-compatible second-source is documented from another manufacturer; the part is single-sourced from TI.
