It accepts CML, LVDS, or LVPECL input levels and outputs LVDS, making it a flexible signal-conditioning block for backplane, cable, or clock distribution applications where signal integrity degrades over distance. Each channel supports a maximum data rate of 800 Mbps, with a propagation delay of 2.0 ns and input capacitance of 3.5 pF. For new designs or BOM lines requiring this exact order code, procurement must rely on independent distribution channels. ## 800 Mbps per channel — timing and signal-integrity budget At 800 Mbps, the per-channel bit period is 1.25 ns. The 2.0 ns propagation delay is a fixed latency through the device, not a timing uncertainty — it adds to the total path delay but does not reduce the data eye. The real margin driver is the device's ability to re-drive the signal with LVDS levels, restoring edge rates and voltage swing after a lossy transmission line. For a backplane trace or cable run that has attenuated the original signal, this reDriver recovers the eye opening so the receiver sees a clean differential swing. The 3.5 pF input capacitance is low enough to avoid loading the upstream driver excessively at these rates. ## Input flexibility and supply rail The DS90LV804TSQX accepts three common differential signaling standards on its inputs: CML, LVDS, and LVPECL. The output is always LVDS, which is the standard for low-noise, high-speed point-to-point links. The supply range is 3.15 V to 3.45 V, so a nominal 3.3 V rail is within tolerance. The 117 mA supply current is the total for all four channels active; thermal design should account for this in the 32-WQFN package with the exposed pad soldered to a PCB copper plane.","metaTitle":"DS90LV804TSQX LVDS Buffer/ReDriver, 800 Mbps, 4-Channel","metaDescription":"DS90LV804TSQX is a 4-channel LVDS buffer/reDriver supporting 800 Mbps per channel.
