1.5 Gbps LVDS redriver in a 3x3 mm WSON
The DS15BA101SDE/NOPB is a single-channel LVDS buffer and signal conditioner from Texas Instruments, designed to extend the reach of high-speed differential signals across a backplane or cable. It accepts CML, LVDS, or LVPECL input levels and re-drives them as CML or LVDS outputs, with a maximum data rate of 1.5 Gbps. The 1.1 ns propagation delay sets the timing budget for the link — at 1.5 Gbps the bit period is 667 ps, so the part adds less than two bit-times of latency, which is negligible for most serial links but must be accounted for in closed-loop timing or daisy-chained repeater topologies.
Signal conditioning and supply budget
The input common-mode range accommodates LVDS (350 mV typical swing) and LVPECL (800 mV swing) without external level shifting — the internal termination and bias network handles the offset.
Sourcing and compliance
Texas Instruments lists the DS15BA101SDE/NOPB as an active product with ROHS3 compliance.
