SEMICONDUCTOR TECHNICAL DATA

Triple ECL to PECL Translator

receives either standard or low voltage differential ECL signals and

translates them to either standard or low voltage differential PECL output

signals. The LVEL device can handle the low voltage signals while the EL

device is designed for the standard signals. It is possible to have low

voltage signals on one side and standard signals on the other if the

LVEL90 is used.

at the input. If a single ended input is to be used the V BB output should be

connected to the D input. The active signal would then drive the D input.

When used the V BB output should be bypassed to ground via a 0.01 F

capacitor. The V BB output is designed to act as the switching reference

for the EL90 under single ended input switching conditions, as a result

this pin can only source/sink up to 0.5mA of current.

power rails. The V CC supply should be connected to the positive supply,

and the V EE pin should be connected to the negative power supply. The

GND pins as expected are connected to the system ground plain. Both

V EE and V CC should be bypassed to ground via 0.01 F capacitors.

the D input will be pulled to V EE . This condition will force the Q output to a

LOW, ensuring stability.

The MC100LVEL/EL90 is a triple ECL to PECL translator. The device

A V BB output is provided for interfacing with single ended ECL signals

To accomplish the level translation the EL/LVEL90 requires three

Under open input conditions, the D input will be biased at V EE /2 and
