General Description
The MAX9157 is a quad bus LVDS (BLVDS) transceiver
for heavily loaded, half-duplex multipoint buses. Small
32-pin QFN and TQFP packages and flow-through
pinouts allow the transceiver to be placed near the con-
nector for the shortest possible stub length. The
MAX9157 drives LVDS levels into a 27
load (double
terminated, heavily loaded LVDS bus) at up to
200Mbps. An input fail-safe circuit ensures the receiver
output is high when the differential inputs are open, or
undriven and shorted, or undriven and terminated. The
MAX9157 differential inputs feature 52mV hysteresis for
greater immunity to bus noise and reflections. The
MAX9157 operates from a single 3.3V supply, consum-
ing 80.9mA supply current with drivers enabled, and
22.7mA with drivers disabled.
The MAX9157’s high-impedance I/Os (except for
receiver outputs) when V
CC
= 0 or open, combined
with glitch-free power-up and power-down, allow hot
swapping of cards in multicard bus systems; 7.2pF
(max) BLVDS I/O capacitances minimize bus loading.
The MAX9157 is offered in 5mm
5mm 32-pin QFN and
TQFP packages. The MAX9157 is fully specified for the
-40°C to +85°C extended temperature range. Refer to
the MAX9129 data sheet for a quad BLVDS driver, ideal
for dual multipoint full-duplex buses.
