Semiconductor Group

DESCRIPTION

The Siemens ESCON/SBCON optical devices, along with the

ESCON / SBCON optical duplex connector, are best suited for

high speed fiber optic duplex transmission systems operating

at a wavelength of 1300 nm. The system is fully compatible

with the IBM ESCON standard and the SBCON standard of

ANSI. It includes a transmitter and a receiver for data rates of

up to 320 MBaud. A non-dissipative plastic receptacle matches

the ESCON/SBCON duplex connector.

The inputs/outputs are PECL compatible and the unit operates

from a single power supply of 3.0 V to 5.5 V. As an option, the

data output stages can be switched to static low levels during

absence of light as indicated by the Signal Detect function.

The optical interface of transmitter and receiver have standard

0.7” spacing. The receptacle and connector have been keyed in

order to prevent reverse insertion of the connector into the

receptacle. After proper insertion the connector is securely held

by a snap-in lock mechanism.

The transmitter converts a serial electrical PECL input signal

with data rates of up to 320 MBaud to an optical serial signal.

The receiver converts this signal back to an electrical serial

signal, depending on the detected optical rate.

APPLICATION NOTE

Power Supply Filtering

In most of the applications using ESCON 200 MBd optical

transceivers additional high speed circuits such as switching

power supply, clock oscillator, or high speed multiplexer are

present on the application board. These often create power

supply noise at a high spectral bandwidth caused by very fast

transitions in today’s chip technology.

The Siemens ESCON Transceiver Family provides superior EMI

performance with regards to the emission and immission of

radiation and provides immunity against conductive noise. Some

basic recommendations are presented herein to ensure proper

functionality in the field.

Receiver Section

For the receiver part of an ESCON transceiver the footprint

shows 2 power supply sections:

VCC1 (Pin 24) and VCC2 (Pins 26,27).

VCC1 is the power supply for the post amplifier and the ECL

output stages of the receiver. VCC2 supplies more sensitive

parts of the receiver.

Pins 26 and 27 are the supply pins for the preamplifier and the

bias for the photodiode.

Transmitter Section

The transmitter consists of only one power supply. Its LED diode

driving current is in the range of 60mA. This is very high

compared to the switching currents on the receiver section.

To buffer these peaks, external capacitors are recommended.

Capacitors will also reduce ringing on the power supply of the

customer‘s board.

Transceiver Filtering

For overall functionality, the sensitive stage of the receiver

section (VCC2) must be decoupled from the output stages and

from high switching currents on the transmitter section.

Filtering Circuitry

The use of SMD components is recommended.

Common layout rules, such as short connection between capac-

itors and pins, ground layers etc., should be applied for optimum

board design and operation.
