Description

The RCV1551 receiver provides optical signal conversion and processing. It contains an InGaAs PIN photodiode and high sensitivity, wide dynamic range, transimpedance amplifier, capacitively coupled to limiting amplifier stages with PECL output drivers. Also provided is a loss of signal alarm. The planar PIN photodiode operates throughout the 1200 nm to 1600 nm wavelength band. A CMOS wide dynamic range transimpedance amplifier optimized for 155 MBd operation provides low noise front end gain for the RCV1551. A low pass filter maximizes the signal to noise ratio while minimizing intersymbol interference. The interface amplifier provides signal conversion and buffering for the PECL complementary data outputs. A complementary PECL alarm output is also provided. The receiver operates from +5 V and -5.2 V or +5 V and Ground power supplies. A 50/125 micron multimode fiber pigtail is included, assuring compatibility with multimode and single mode fiber optic systems.

+5 V FIBER PIGTAIL Connection Diagram Top View Pin Descriptions Pins 5, 17, 18, 19, 20 NC: These pins are not connected and should be left open circuit on the application PCB. Pins 1, 2, 3, 4, 6, 8, 13, 15, 16 GND: These pins should be connected to the circuit ground. Pins 7, 9, DATA, DATA: These pins provide complemen- tary PECL DATA and DATA outputs. The DATA output is noninverting, an optical pulse causes the DATA output to go to the PECL logic high state (+4 V nominal). Pin 10, PD Bias: This pin must be connected to any voltage from 0 V (GND) to -5 V. This provides the photodiode bias. The current drawn is directly proportional to the average received photocurrent. I = Responsitivity x Mean Power. The responsivity will be between 0.7 A/W and 1.0 A/W. Pin 11, +5 V: This pin should be connected to +5 V supply. The network shown below should be placed as close as possible to pin 11. Pins 12, 14 ALARM, ALARM: These pins provide complemen- tary differential ALARM and ALARM outputs. This is the low light alarm. ALARM goes to a logic low (3.3 V nominal) state when the optical power drops below the threshold level (insufficient optical power). The optical power must increase to a higher level than the level where the alarm went low before ALARM will return to a logic high. This difference is the alarm hysteresis. 1 µH +5 V 100 nF 100 nF10 µFPIN 11

Performance Specifications Absolute Limiting Ratings Absolute maximum limits mean that no catastrophic damage will occur if the product is subjected to these ratings for short periods, provided that each limiting parameter is in isolation and all other parameters have values within the performance specification. It should not be assumed that limiting values of more than one parameter can be applied to the product at the same time.
