DS90C031B Datasheet | Texas Instruments

FEATURES - 2 >155.5 Mbps (77.7 MHz) switching rates - High impedance LVDS outputs with power-off - ±350 m V differential signaling - Ultra low power dissipation - 400 ps maximum differential skew (5V, 25°C) - 3.5 ns maximum propagation delay - Industrial operating temperature range - Pin patible with DS26C31, MB571 (PECL) and 41LG (PECL) - Conforms to ANSI/TIA/EIA-644 LVDS standard - Offered in narrow body SOIC package - Fail-safe logic for floating inputs DESCRIPTION The DS90C031B is a quad CMOS differential line driver designed for applications requiring ultra low power dissipation and high data rates. The device supports data rates in excess of 155.5 Mbps (77.7 MHz) and uses Low Voltage Differential Signaling (LVDS) technology. The DS90C031B accepts TTL/CMOS input levels and translates them to low voltage (350 m V) differential output signals. In addition the driver supports a TRISTATE 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 11 m W typical. In addition, the DS90C031B provides power-off high impedance LVDS outputs. This feature assures minimal loading effect on the LVDS bus lines when VCC is not present. The DS90C031B and panion line receiver (DS90C032B) provide a new alternative to high power pseudo-ECL devices for high speed point-topoint interface applications.
