描述 The DS90LV031A is a quad CMOS 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 DS90LV031A 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 EN and EN* inputs allow active Low or active High control of the TRI-STATE outputs. The enables are common to all four drivers. The DS90LV031A and companion line receiver (DS90LV032A) provide a new alternative to high power psuedo-ECL devices for high speed point-to-point interface applications.特性High impedance LVDS outputs with power-off Low differential skew Low propagation delay 3.3V power supply design ±350 mV differential signaling Low power dissipation Interoperable with existing 5V LVDS devices Compatible with IEEE 1596.3 SCI LVDS standard Compatible with proposed TIA/EIA-644 LVDS standard Pin compatible with DS26C31 Typical Rise/Fall times of 800pS.
