MAX3901D Overview

150Mbps Automotive Fiber Optic Receivers

19-3278; Rev 1; 7/04
150Mbps Automotive Fiber Optic Receivers
General Description
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 -40°C to +140°C (junction) temperature range.
The MAX3901 features a 1.2µA 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 1.2µA to 1mA input range,
+3.3V supply voltage, operation from 40Mbps to
150Mbps, and a differential output compatible with
LVDS, PECL, and IEEE 1394b (S100β).
Both circuits provide an input power detect and low-
power 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.
