125 Megabaud Fiber Optic Link

Transmitter/Receiver

CAUTION: The small junction sizes inherent to the design of this component increase the component's suscepti-

bility to damage from electrostatic discharge (ESD). It is advised that normal static precautions be taken in

handling and assembly of this component to prevent damage and/or degradation which may be induced by

ESD.

Description

The HFBR-5527 incorporates a

650 nm LED, a PIN photodiode,

and transimpedance preamplifier.

The 650 nm LED is suitable for

use with current peaking to

decrease optical response time

and can be used with the PIN

preamplifier to build an optical

transceiver that can be operated

at signaling rates from 1 to 125

receivers convert a received

optical signal to an analog output

voltage. Follow-on circuitry can

optimize link performance for a

variety of distance and data rate

requirements. Electrical

bandwidth greater than 65 MHz

allows design of high speed data

links with plastic or hard clad

silica optical fiber.

WARNING: WHEN VIEWED UNDER SOME CONDITIONS, THE OPTICAL PORT MAY

EXPOSE THE EYE BEYOND THE MAXIMUM PERMISSIBLE EXPOSURE RECOMMENDED

IN ANSI Z136.2, 1993. UNDER MOST VIEWING CONDITIONS THERE IS NO EYE HAZARD.
