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 lownoise
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 to +85°C.
