General Description
The MAX9158 is a quad bus LVDS (BLVDS) transceiver
for heavily loaded, half-duplex multipoint buses. A 44-
lead QFN package and flow-through pinout allow the
transceiver to be placed near the connector. The
MAX9158 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
MAX9158 operates from a single 3.3V supply, consum-
ing 77mA supply current with drivers enabled, and
19.9mA with drivers disabled.
The MAX9158’s high-impedance I/Os (except for receiver
outputs) when V
CC
= 0V or open, combined with glitch-
free power-up and power-down, allow hot swapping of
cards in multicard bus systems; 7.3pF (max) BLVDS I/O
capacitance minimizes bus loading.
The MAX9158 is offered in a 7mm
7mm 44-lead QFN
package, and is fully specified for the -40°C to +85°C
extended temperature range. Refer to the MAX9157 data
sheet for a quad BLVDS transceiver with hysteresis in 32-
lead QFN and TQFP packages. Refer to the MAX9129
data sheet for a quad BLVDS driver, ideal for dual multi-
point full-duplex buses.
