SEMICONDUCTOR TECHNICAL DATA
The MC100LVEL/EL91 is a triple PECL to ECL translator. The
MC100L VEL91 receives low voltage PECL signals and translates them to
differential ECL output signals. The MC100EL91 receives standard
voltage PECL signals and translates them to differential ECL output
signals.
• MC100LVEL91 Supports Low Voltage Operation
• MC100LVEL91 Has 620ps Typical Propagation Delays
• MC100EL91 Supports Standard Voltage Operation
• MC100EL91 Has 670ps Typical Propagation Delays
• Fully Dif ferential Design
• 20–lead SOIC Packaging
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
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 EL/LVEL91 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 EL/LVEL91 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 are connected to the system ground plain. Both VEE and V
should be bypassed to ground via 0.01µF capacitors.
Under open input conditions, the D
the D input will be pulled to GND. This condition will force the Q output to
a low, ensuring stability.
input. The active signal would then drive the D input.
