MAX9157EHJ+ by Analog Devices

Quad Bus LVDS Transceiver


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 connector for the shortest possible stub length. The MAX9157 drives LVDS levels into a 27Ω 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, consuming 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 VCC = 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 x 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.
