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 -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. o Operation Up to 50Mbps (MAX3901) o Operation Up to 150Mbps (MAX3902) o +3.3V or +5.0V Power Supply (MAX3901) o 1.2AP-P Input Sensitivity o 1mAP-P Input Overload o Input Power Detect with Power-Reducing Standby Mode o Active Output Pulldown During Standby Mode (MAX3901) o Differential LVDS- or PECL-Compatible Output (MAX3902) o TTL-Compatible Output (MAX3901) o No Filter Capacitors Required in the Optical Subassembly

TTL Data Output. Current flowing into IN causes the voltage at OUT_TTL to increase.
Detailed Description
The MAX3901/MAX3902 receivers are optimized for automotive fiber optic applications. The MAX3901 is a single-ended TTL output receiver. The MAX3902 is a differential CML output receiver. The MAX3901/ MAX3902 are both comprised of a transimpedance amplifier, a voltage-gain amplifier, an output buffer, a DC cancellation circuit, and a power detector with status monitor, as shown in Figure 2.
CML Output Buffer
The output buffer for the MAX3902 is a differential CML output designed to drive a 100 differential load between OUT+ and OUT- (Figure 3). For optimum supply noise rejection, the MAX3902 should be terminated with a differential load. If a single-ended output is required, both the used and the unused outputs should be terminated in a similar manner.
Signal Path
The signal path consists of a transimpedance amplifier, a voltage-gain amplifier, and a DC cancellation circuit. The transimpedance amplifier converts input current to voltage. The voltage-gain amplifier converts single-ended to differential voltage. The DC cancellation circuit uses lowfrequency feedback to remove the DC component of the input signal. This feature centers the input signal within the transimpedance amplifier's linear range, thereby reducing pulse-width distortion. The highpass response of the DC cancellation circuit limits the number of consecutive identical digits that can be tolerated.

TTL Output Buffer
The output buffer for the MAX3901 is a single-ended TTL output designed to drive a high-impedance load. Output capacitance should be less than 15pF to ensure stable operation. The TTL output is not compatible with 50 test equipment. Use a high-impedance probe to monitor the output. During standby mode, the TTL output is actively pulled to a low state.

Status Monitor
The MAX3901/MAX3902 include a status monitor (Figure 4). The average current at the FILT (Figure 5) pad determines whether the MAX3901/MAX3902 are in operating or standby mode. STATUS is TTL low when the receiver is in operating mode. STATUS is TTL high when the receiver is in standby mode.

Applications Information
Optical Power Relations
MAX3902
Many of the MAX3901/MAX3902 specifications relate to the input signal amplitude. Figure 6 and Table 1 show relations that are helpful for converting optical power to input signal when designing with the MAX3901/ MAX3902.

Wire Bonding
For high-current density and reliable operation, the MAX3901 and MAX3902 use gold metalization. For best results, use gold-wire ball-bonding techniques. Use caution if attempting wedge bonding. Bond-pad size is 94.4m x 94.4m, and bond-pad metal thickness is 1.2m. Refer to Maxim Application Note, HFAN08.0.1: Understanding Bonding Coordinates and Physical Die Size for additional information.
