This is a single-channel buffer and re-driver that accepts CML, LVDS, or LVPECL input levels and re-transmits a LVPECL output. The 2 Gbps maximum data rate covers common serial standards such as Gigabit Ethernet, Fibre Channel, and high-speed backplane links. The 630 ps propagation delay is the additive latency through the device — budget it into your timing closure for multi-drop clock or data distribution. At 50 mA supply current from a 3.0 V to 3.6 V rail, the power dissipation is modest for a 2 Gbps re-driver.
Input capacitance is 0.6 pF, which helps maintain signal integrity at the receiver node.
