4 Gbps PECL-to-LVDS reDriver — what the delay and data rate mean for the link
It is designed for high-speed serial links where signal conditioning is needed to recover eye margin across a backplane or cable. The 4 Gbps maximum data rate and 460 ps propagation delay define the timing budget: at 4 Gbps the unit interval is 250 ps, so the 460 ps delay is roughly 1.8 UI — you need to account for that in the link timing closure, not just the edge rate.
Package and footprint — 8-WSON with exposed pad
Surface-mount only; the small 2 mm x 2 mm footprint fits dense boards where a larger SOIC or MSOP would not route.
