DESCRIPTION
The SY100EL90V is a triple ECL/LVECL-to-PECL/ LVPECL translator. The device can translate over all binations of supply voltages: -5V ECL to 5V PECL, -5V ECL to 3.3V LVPECL, -3.3V LVECL to 5V PECL or -3.3V LVECL to 3.3V LVPECL.
A VBB output is provided for interfacing with single ended ECL 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 via a 0.01µF capacitor. The VBB output is designed to act as the switching reference for the EL90V under single ended input switching conditions. As a result this pin can only source/sink up to 0.5m A of current.
To acplish the level translation the EL90V requires three power rails. The VCC supply should...
