The MAX3901/MAX3902 are optimized for low-cost polymer-clad silica (PCS) and plastic optical fiber (POF) automotive receivers. These parts operate over an extended -40C to +140C (junction) temperature range. The MAX3901 features a 1.2A to 1mA input range, a +3.3V or +5V supply voltage, operation from 8Mbps to 50Mbps, and a TTL output compatible with common automotive optical network interfaces. The MAX3902 features a 1.2A to 1mA input range, +3.3V supply voltage, operation from 40Mbps to 150Mbps, and a differential output compatible with LVDS, PECL, and IEEE 1394b (S100). Both circuits provide an input power detect and lowpower standby mode with status output. No filter capacitors are required in the optical subassembly, thus enabling a low-cost receiver design. The circuits are available in die and wafer form.
