DS90LV012A/DS90LT012A  
3V LVDS Single CMOS Differential Line Receiver  
General Description  
Features  
n Compatible with ANSI TIA/EIA-644-A Standard  
The DS90LV012A and DS90LT012A are single CMOS differ-  
ential line receivers designed for applications requiring ultra  
low power dissipation, low noise, and high data rates. The  
devices are designed to support data rates in excess of 400  
Mbps (200 MHz) utilizing Low Voltage Differential Swing  
(LVDS) technology  
>
n
400 Mbps (200 MHz) switching rates  
n 100 ps differential skew (typical)  
n 3.5 ns maximum propagation delay  
n Integrated line termination resistor (102typical)  
n Single 3.3V power supply design (2.7V to 3.6V range)  
n Power down high impedance on LVDS inputs  
n Accepts small swing (350 mV typical) differential signal  
levels  
n LVDS receiver inputs accept LVDS/BLVDS/LVPECL  
inputs  
n Supports open, short and terminated input fail-safe  
n Pinout simplifies PCB layout  
The DS90LV012A and DS90LT012A accept low voltage (350  
mV typical) differential input signals and translates them to  
3V CMOS output levels. The receivers also support open,  
shorted, and terminated (100) input fail-safe. The receiver  
output will be HIGH for all fail-safe conditions. The  
DS90LV012A has a pinout designed for easy PCB layout.  
The DS90LT012A includes an input line termination resistor  
for point-to-point applications.  
@
n Low Power Dissipation (10mW typical 3.3V static)  
n SOT-23 5-lead package  
The DS90LV012A and DS90LT012A, and companion LVDS  
line driver provide a new alternative to high power PECL/  
ECL devices for high speed interface applications.  
n Leadless LLP-8 package (3x3 mm body size)  
n SOT version pin compatible with SN65LVDS2,  
SN65LVDT2  
n Electrically similar to the DS90LV018A  
n Fabricated with advanced CMOS process technology  
n Industrial temperature operating range  
(−40˚C to +85˚C)
