1.5 Gbps data rate and 440 ps delay — what they mean for the link
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.
Active lifecycle — no LTB risk for new designs
The DS10BR254TSQ/NOPB carries an Active lifecycle status and is ROHS3 compliant.
Package and mounting — 40-WFQFN with exposed pad
The part comes in a 40-lead WFQFN with an exposed pad. The pad must be soldered to a copper land on the PCB and connected to ground with multiple thermal vias. 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. The supplier device package is listed as 40-WQFN (6x6) — same footprint, different suffix in the TI ordering tree.
