| Micrel, Inc. 5V/3.3V TRIPLE ECL/LVECL-TOPECL/LVPECL TRANSLATOR SY100EL90V SY100EL90V s 3.3V and 5V power supply options s 500ps propagation delay s Fully differential design s Supports both standard and low voltage operation s Available in 20-pin SOIC package The SY100EL90V is a triple ECL/LVECL-to-PECL/ LVPECL translator. The device can translate over all combinations 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 0.5mA of current. To accomplish the level translation the EL90V 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 VEE. This condition will force the Q output to a LOW, ensuring stability.
