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.

Jitter Test Pattern
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

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.
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
