At 1.5 Gbps the DS10BR254TSQ/NOPB handles protocols like Gigabit Ethernet, SATA Gen 1, or LVDS-based serial video links without retiming. The 440 ps propagation delay is the time from input crossing to output switching — it adds directly to the link's total latency. In a multi-drop clock fan-out, that delay is deterministic and matched across channels, so skew between outputs stays within the part's inherent matching. The 1.7 pF input capacitance keeps the loading light on the driving source, which matters when the upstream driver is already driving a long backplane trace.
Package and mounting — 40-WFQFN with exposed pad
The part comes in a 40-lead WFQFN with an exposed pad. Without that thermal path, the junction temperature rises above the rated operating range under full data-rate switching. The package is 6x6 mm, so it fits in tight channel spacing on a line card.
