1 General Description
The AS1153/55/57/58 are Single/Dual flow-through
LVDS (low-voltage differential signaling) receivers which
accept LVDS differential inputs and convert them to
LVCMOS outputs. The receivers are perfect for low-
power low-noise applications requiring high signaling
rates and reduced EMI emissions.
The devices are guaranteed to receive data at speeds
up to 260Mbps (130MHz) over controlled impedance
media of approximately 100Ω. Supported transmission
media are PCB traces, backplanes, and cables.
The AS1155/58 are single LVDS receivers, and the
AS1153/57 are dual LVDS receivers.
The AS1157/58 features integrated parallel termination
resistors (nominally 107Ω), which eliminate the require-
ment for discrete termination resistors, and reduce stub
lengths. The AS1153/55 uses high impedance inputs
and requires an external termination resistor when used
in a point-to-point connection.
The integrated Failsafe feature sets the output high if the
inputs are open, undriven and terminated, or undriven
and shorted.
All inputs conform to the
ANSI TIA/EIA- 644
LVDS stan-
dards. Flow-through pinout simplifies PC board layout
and reduces crosstalk by separating the LVDS inputs
and LVCMOS outputs.
The devices are available in a 8-pin SOIC package.
