DESCRIPTION

OUTLINE DIMENSIONS in inches (mm)

Next Generation detectors are designed for use in IEEE

802.3 Ethernet and IEEE 802.5J Token Ring applications

such as repeaters, bridges, hubs, routers, switches and

gateways. This inexpensive, high speed analog fiber

optic receiver is intended for use in local area networks

(LANs) where data rates up to 125 Mbits/second are

needed, and could be used as a low cost alternative to

1300 nm components. The hybrid bipolar fiber optic

receiver contains a silicon PIN photodiode for high speed

operation and a preamplifier integrated circuit for

excellent noise immunity.

The preamplifier stage of the Next Generation detector

converts the current output of the PIN photodiode to a

voltage and amplifies it. The output is a linear voltage

proportional to the optical input over an input range of

less than 1.0 µW to 175 µW peak (1.313 V typical output

voltage swing) providing a dynamic operating range of

23 dB with very low pulse-width distortion.

The receivers are designed to operate on the ECL

standard of -5.2 volts and have very good Power Supply

Rejection Ratio (typically 20 dB at 10 MHz), making them

highly immune to noise pickup. They can also be

operated with a +5 volt supply although some PSRR

performance will be sacrificed at less than 1 MHz.

The receiver output is a proportional analog voltage,

providing cost-effective design flexibility. The circuit

design can be tailored to a particular application, using

inexpensive external components to perform the

conversion to the needed logic levels. This allows for

optimized design, making maximum use of the power

budget for a given data rate/transmission distance

configuration.

ST is a registered trademark of AT & T.

The connector can act as a shield. For optimum EMI

shielding, stake pins should be connected to chassis ground.

Signal ground and chassis ground should be bridged with a

high Q 0.01µF capacitor at the fiber optic component.

Honeywell reserves the right to make

changes in order to improve design and

431

supply the best products possible.
