AB1432 Datasheet 50mb/s Fiber Optic Receivers

Manufacturer: Philips Semiconductors (now NXP Semiconductors)

Overview: INTEGRATED CIRCUITS AB1432 50Mb/s fiber optic receivers Author: G. Lane 1988 Dec Philips Semiconductors Philips Semiconductors Application brief 50Mb/s fiber optic receivers Author: G. Lane INTRODUCTION This application brief describes the use of four Philips Semiconductors devices specifically designed for use as fiber optic receiver ponents. In order to simplify the design process for a prospective user, two typical fiber optic receivers were designed, built and tested. The design criteria for these receivers is a maximum of 50Mb/s data rate non-return-to-zero (NRZ) format, optical wavelength of 850nm, and readily available ponents. The two receivers are topologically similar; the difference between them is in performance, which will be pointed out in the specific discussion of each receiver. For ease of explanation, two sets of schematic diagrams are used.

General Description

of the circuit operation.

The second, and plete set, shows the peripheral ponents and the power supply decoupling networks.

The choice of which preamplifier to use with which postamplifier is determined by the task to be acplished.
