Device Overview

Summary

The SY100EL91 is a triple PECL-to-ECL translator. It receives standard voltage PECL signals and translates them to different ECL output signals.A VBB output is provided for interfacing with single ended PECL signals at the input. If a single ended input is to be used, the VBB output should be connected to the D input. The active signal would then drive the D input.When used, the VBB output should be bypassed to ground via a 0.01µF capacitor. The VBB output is designed to act as the switching reference for the EL91 under single ended input switching conditions.

As a result this pin can only source/sink up to 0.5mA of current.To accomplish the level translation the EL91 requires three power rails. The VCC supply should be connected to the positive supply, and the VEE pin should be connected to the negative power supply. The GND pins as expected are connected to the system ground plane. Both VEE and VCC should be bypassed to ground via 0.01µF capacitors.Under open input conditions, the D input will be biased at VCC/2 and the D input will be pulled to GND. This condition will force the Q output to a LOW, ensuring stability.
