The AS1150 and AS1151 are quad flow-through LVDS
(low-voltage differential signaling) receivers which
accept LVDS differential inputs and convert them to
LVCMOS outputs. The receivers are perfect for lowpower
low-noise applications requiring high signaling
rates and reduced EMI emissions.
The devices are guaranteed to receive data at speeds
up to 500Mbps (250MHz) over controlled impedance
media of approximately 100Ω. Supported transmission
media are PCB traces, backplanes, and cables.
The AS1150 uses high impedance inputs and requires
an external termination resistor when used in a point-topoint
connection. The AS1151 features integrated parallel
termination resistors (nominally 107Ω), which eliminate
the requirement for discrete termination resistors,
and reduce stub lengths.
The integrated failsafe feature sets the output high if the
inputs are open, undriven and terminated, or undriven
and shorted. Enable inputs (EN and ENn – internally
pulled down to GND) control the high-impedance output
and are common to all four receivers. All inputs conform
to the ANSI TIA/EIA- 644 LVDS standards. Flow-through
pinout simplifies PC board layout and reduces crosstalk
by separating the LVDS inputs and LVCMOS outputs.
The devices are available in a 16-pin TSSOP package.
