Datasheet

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 100

Ω.

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.
