DS90LV047A 3V LVDS Quad CMOS Differential Line Driver July 1999 DS90LV047A 3V LVDS Quad CMOS Differential Line Driver General Description The DS90LV047A is a quad CMOS flow-through differential line driver designed for applications requiring ultra low power dissipation and high data rates. The device is designed to support data rates in excess of 400 Mbps (200 MHz) utilizing Low Voltage Differential Signaling (LVDS) technology. The DS90LV047A accepts low voltage TTL/CMOS input levels and translates them to low voltage (350 mV) differential output signals. In addition, the driver supports a TRI-STATE ® function that may be used to disable the output stage, disabling the load current, and thus dropping the device to an ultra low idle power state of 13 mW typical. The DS90LV047A has a flow-through pinout for easy PCB layout. The EN and EN* inputs are ANDed together and control the TRI-STATE outputs. The enables are common to all four drivers. The DS90LV047A and companion line receiver (DS90LV048A) provide a new alternative to high power psuedo-ECL devices for high speed point-to-point interface applications.
