Description
SK1527
Anything to PECL Translator
PRELIMINARY
.eatures
The SK1527 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 or voltage level. The D - flip-flop is
triggered on the falling edge of the clock.
The SK1527 uses 50Ω outputs with source /sink
capability, and is optimized for:
• High speed clock / data lines
that require translation
• Point to point, double termination
applications
