5V/3.3V TRIPLE ECL/LVECL-TO-  
PECL/LVPECL TRANSLATOR  
SY100EL90V  
FEATURES  
DESCRIPTION  
3.3V and 5V power supply options  
500ps propagation delay  
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.  
Fully differential design  
Supports both standard and low voltage operation  
Available in 20-pin SOIC package  
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.
