DESCRIPTION
l l l l l l l l l l l l l l l
The TRS-73120G series single mode transceivers is low power, high performance module for bi-directional serial optical data communications such Gigabit Ethernet and Fibre Channel. This module is designed for single mode fiber and operates at a nominal wavelength of 1550 nm. A guaranteed minimum optical link budget of 32 dB is offered which can correspond to a link distance of over 120 km (assuming worst case fiber loss of 0.25 dB/km). The transmitter section uses a multiple quantum well laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated InGaAs Avalanche photodetector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC. A PECL logic interface simplifies interface to external circuitry.

For TTL SD Level, R1=R2=N.C., R7=100 ohm For PECL SD Level, R1=130 ohm, R2=82 ohm, R7=100 ohm The split-load terminations for ECL signals need to be located at the input of devices receiving those ECL signals. The power supply filtering is required for good EMI performance. Use short tracks from the inductor L1/L2 to the module Rx Vcc and Tx Vcc. A GND plane under the module is required for good EMI and sensitivity performance.
