FEATURES
DESCRIPTION
The DS90LV047A is a quad CMOS flow-through
2
• >400 Mbps (200 MHz) Switching Rates
differential line driver designed for applications
• Flow-Through Pinout Simplifies PCB Layout
requiring ultra low power dissipation and high data
• 300 ps Typical Differential Skew
rates. The device is designed to support data rates in
excess of 400 Mbps (200 MHz) utilizing Low Voltage
• 400 ps Maximum Differential Skew
Differential Signaling (LVDS) technology.
• 1.7 ns Maximum Propagation Delay
The DS90LV047A accepts low voltage TTL/CMOS
• 3.3V Power Supply Design
input levels and translates them to low voltage (350
• ±350 mV Differential Signaling
mV) differential output signals. In addition, the driver
• Low Power Dissipation (13mW at 3.3V Static)
supports a TRI-STATE function that may be used to
disable the output stage, disabling the load current,
• Interoperable with Existing 5V LVDS Receivers
and thus dropping the device to an ultra low idle
• High impedance on LVDS Outputs on Power
power state of 13 mW typical. The DS90LV047A has
Down
a flow-through pinout for easy PCB layout.
• Conforms to TIA/EIA-644 LVDS Standard
The EN and EN* inputs are ANDed together and
• Industrial Operating Temperature Range
control the TRI-STATE outputs. The enables are
(−40°C to +85°C)
common to all four drivers. The DS90LV047A and
companion line receiver (DS90LV048A) provide a
• Available in Surface Mount (SOIC) and Low
new alternative to high power psuedo-ECL devices
Profile TSSOP Package
for high speed point-to-point interface applications.
