Description

SK1528

Anything to ECL Translator

PRELIMINARY

.eatures

The SK1528 is an extremely fast, stable, and accurate •

low skew 1:5 clock / signal distributor featuring a •

synchronous enable, which allows the outputs to be •

turned off and on without the risk of an upredictable

output pulse. It is also capable of receiving inputs of

any technology and voltage level. The D - flip-flop is

triggered on the falling edge of the clock.

The SK1528 has 50Ω outputs with source /sink

capability, and is optimized for:

• High speed clock / data lines that

require translation

• Point to point, double termination

applications
