DS90C031B LVDS Quad CMOS Differential Line Driver

Check for Samples: DS90C031B

FEATURES

DESCRIPTION

The DS90C031B is a quad CMOS differential line

• >155.5 Mbps (77.7 MHz) switching rates

driver designed for applications requiring ultra low

• High impedance LVDS outputs with power-off

power dissipation and high data rates. The device

• ±350 mV differential signaling

supports data rates in excess of 155.5 Mbps (77.7

MHz) and uses Low Voltage Differential Signaling

• Ultra low power dissipation

(LVDS) technology.

• 400 ps maximum differential skew (5V, 25°C)

The DS90C031B accepts TTL/CMOS input levels and

• 3.5 ns maximum propagation delay

translates them to low voltage (350 mV) differential

• Industrial operating temperature range

output signals. In addition the driver supports a TRI-

• Pin compatible with DS26C31, MB571 (PECL)

STATE function that may be used to disable the

and 41LG (PECL)

output stage, disabling the load current, and thus

dropping the device to an ultra low idle power state of

• Conforms to ANSI/TIA/EIA-644 LVDS standard

11 mW typical.

• Offered in narrow body SOIC package

In addition, the DS90C031B provides power-off high

• Fail-safe logic for floating inputs

impedance LVDS outputs. This feature assures

minimal loading effect on the LVDS bus lines when

is not present.

The DS90C031B and companion line receiver

(DS90C032B) provide a new alternative to high

power pseudo-ECL devices for high speed point-to-

point interface applications.

DS90C031B www.ti.com SNLS051B – MARCH 1999 – REVISED MARCH 2013 APPLICATIONS INFORMATION LVDS drivers and receivers are intended to be primarily used in an uncomplicated point-to-point configuration as is shown in Figure 7. This configuration provides a clean signaling environment for the quick edge rates of the drivers. The receiver is connected to the driver through a balanced media which may be a standard twisted pair cable, a parallel pair cable, or simply PCB traces.
