AS1152 LVDS Driver IC

Description

The AS1152 is a Quad 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 500Mbps (250MHz) over controlled impedance media of approximately 100Ω. 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) during high impedance. The Enable Inputs are common to all four drivers.

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 AS1152 operates from a single +3.3V supply and is specified for operation from -40°C to +85°C.
