Transmitter Section
The transmitter section consists of a 1300 nm MQW Fabry
Perot Laser in an optical subassembly (OSA), which mates
to the ber optic cable. The Laser OSA is driven by a cus-
tom, silicon bipolar IC which converts dierential PECL
logic signals (ECL referenced to a +5 V supply) into an
analog drive current to the laser.
The laser driver IC incorporates temperature compensa-
tion and feedback from the OSA to maintain constant
output power and extinction ratio over the operating
temperature range.
Receiver Section
The receiver includes a PIN photodiode mounted to-
gether with a custom, silicon bipolar transimpedance
preamplier IC, in an OSA. The OSA interfaces to a
custom silicon bipolar circuit that provides post-ampli-
cation and quantization. The post-amplier includes a
Signal Detect circuit that provides TTL compatible logic-
low output in response to the detection of a usable input
optical signal.
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each
parameter in isolation, all other parameters having values within the recommended operating conditions. It should
not be assumed that limiting values of more than one parameter can be applied to the product at the same time.
Exposure to the absolute maximum ratings for extended periods can adversely aect device reliability.

Eye Safety Design
The laser driver is designed to be Class 1 eye safe
(CDRH21 CFR(J), IEC 60825-1) under a single fault condi-
tion.
There are three key elements to the safety circuitry: a
monitor diode, a window detector circuit, and direct
control of the laser bias. The window detection circuit
monitors the average optical power using the photo
diode in the laser OSA. If a fault occurs such that the dc
bias circuit cannot maintain the preset conditions within
±20%, TX_FAULT (Pin 10) will be asserted (high).
Note: Under any single fault, the laser optical output
power will remain within Class 1 eye safe limits.
