3.3 V, 50 Mbit/s one-chip Si-bipolar transceiver LSI for optical burst-mode communications

Abstract

A 3.3 V, 50 Mbit/s, one-chip transceiver LSI fabricated by a 4 GHz Si-bipolar process includes an adjustment-free instantaneous response receiver and a laser-diode (LD) driver to build a low-cost optical interface module for FTTH systems. The LSI, assembled with a conventional 0.8 A/W photodiode and 0.2 W/A LD, has an input optical receiver range of –37.8 to –17.0 dBm and an optical average output power of +6 dBm.
