The DS90LV049TMT is a dual CMOS flow-through differential Line Driver and Receiver Pair designed for applications requiring ultra low power dissipation, exceptional noise immunity and high data throughput. The device is designed to support data rates in excess of 400Mbps utilizing low voltage differential signalling (LVDS) technology. It accepts LVTTL/LVCMOS signals and translates them to LVDS signals. On the other hand, the receiver accepts LVDS signals and translates them to 3V CMOS signals. The LVDS input buffers have internal failsafe biasing that places the outputs to a known H (high) state for floating receiver inputs. In addition, the DS90LV049 supports a tri-state function for a low idle power state when the device is not in use. The EN and EN inputs are ANDed together and control the tri-state outputs. The enables are common to all four gates.
● Flow-through pin-out simplifies PCB layout

● High impedance on LVDS outputs on power-down
● Low power dissipation (70mW at 3.3V static)
● 50ps Typical driver channel-to-channel skew
● 50ps Typical receiver channel-to-channel skew
