What this LVDS redriver does on a serial link
The 47 mA supply current at 3.3 V is the power budget line item for the LVDS rail — no surprise in a dense telecom or ATE card where every milliamp is accounted for.
800 Mbps and 1.4 ns — what they mean for timing closure
At 800 Mbps the unit interval is 1.25 ns, so the 1.4 ns propagation delay consumes just over one bit period end-to-end. In a daisy-chained repeater topology — say a clock distribution or serial backplane with multiple redrivers — those delays add. The practical takeaway: budget the cumulative delay against your receiver setup-and-hold window, not just the per-device number. The part reconditions the signal edges, so the output jitter is lower than the input; that trade-off is what makes the redriver useful on marginal links.
Industrial temperature and 8-WSON package — layout constraints
The pad is electrically connected to ground, so the via stitch doubles as a low-inductance return path for the high-speed signal loop.
The base product number DS90LV001 covers multiple package and temperature variants; the TLD/NOPB suffix identifies the 8-WSON reel with lead-free plating.
