TRIPLE

PECL-TO-ECL TRANSLATOR

SY100EL91

FEATURES

620ps typical propagation delay

Fully differential design

Supports standard operation

Available in 20-pin SOIC package

DESCRIPTION

The SY100EL91 is a triple PECL-to-ECL translator. It

receives standard voltage PECL signals and translates

them to different ECL output signals.

A V

output is provided for interfacing with single

ended PECL signals at the input. If a single ended input

is to be used, the V

output should be connected to the

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

When used, the V

output should be bypassed to ground

via a 0.01µF capacitor. The V

output is designed to act

as the switching reference for the EL91 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 EL91 requires

three power rails. The V

supply should be connected

to the positive supply, and the V

pin should be

connected to the negative power supply. The GND pins

as expected are connected to the system ground plane.

Both V

and V

should be bypassed to ground via

0.01µF capacitors.

Under open input conditions, the D input will be biased

at V

/2 and the D input will be pulled to GND. This

condition will force the Q output to a LOW, ensuring

stability.
