1 General Description

The AS1152 is a Quad Flow-Through LVDS (Low-Volt-

age 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 500Mbps (250MHz) over controlled impedance media

of approximately 100

Ω. Supported transmission media

are PCB traces, backplanes, and cables.

The AS1152 is capable of setting all four outputs to a

high-impedance state through two Enable Inputs (EN

and ENn – internally pulled down to GND), dropping the

device to an ultra-low-power state of 16mW (typical) dur-

ing high impedance. The Enable Inputs are common to

all four drivers.

Outputs conform to the ANSI TIA/EIA-644 LVDS stan-

dards. Flow-through pinout simplifies PC board layout

and reduces crosstalk by separating the LVTTL/LVC-

MOS inputs and LVDS outputs.

The AS1152 operates from a single +3.3V supply and is

specified for operation from -40 to +85°C.
