DS90LV019 3.3V or 5V LVDS Driver/Receiver General Description Features The DS90LV019 is a Driver/Receiver designed specifically for the high speed low power point-to-point interconnect applications. The device operates from a single 3.3V or 5.0V power supply and includes one differential line driver and one receiver. The DS90LV019 features an independent driver and receiver with TTL/CMOS compatibility (DIN and ROUT).

DS90LV019 Applications Information • (Continued) • Balanced cables (e.g., twisted pair) are usually better than unbalanced cables (ribbon cable, simple coax) for noise reduction and signal quality. • For cable distances < 0.5m, most cables can be made to work effectively. For distances 0.5m ≤ d ≤ 10m, CAT 3 (category 3) twisted pair cable works well and is readily available and relatively inexpensive. For distances > 10m, and high data rates CAT 5 twisted pair is recommended.
