1 General Description
The AS1154 is a dual Flow-Through LVDS (Low-Voltage Differential
Signaling) Line Driver which accepts and converts LVTTL/LVCMOS
input levels into LVDS output signals. The device is perfect for low-
power low-noise applications requiring high signaling rates and
reduced EMI emissions.
The device is guaranteed to transmit data at speeds up to 800Mbps
(400MHz) over controlled impedance media of approximately 100Ω.
Supported transmission media are PCB traces, backplanes, and
cables.
Outputs conform to the
ANSI TIA/EIA-644 LVDS
standards. Flow-
through pinout simplifies PC board layout and reduces crosstalk by
separating the LVTTL/LVCMOS inputs and LVDS outputs.
The AS1154 operates from a single +3.3V supply and is specified for
operation from -40°C to +85°C.
