3 Description

The DSLVDS1047 device is a quad CMOS flowthrough

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) using

Low Voltage Differential Signaling (LVDS)

technology.

The DSLVDS1047 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 DSLVDS1047

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 and companion line

receiver (DSLVDS1048) provide a new alternative to

high power psuedo-ECL devices for high speed pointto-

point interface applications.
