SK1900
1:9 Signal Distribution
HIGH-PERFORMANCE PRODUCTS
Description
Features
The SK1900 is an extremely fast, stable, and accurate
low skew 1:9 clock / signal distributor featuring a
synchronous enable, which allows the outputs to be
turned off and on without the risk of an unpredictable
output pulse. The D - flip-flop is triggered on the falling
edge of the clock.

SK1925
Anything to PECL Translator
HIGH-PERFORMANCE PRODUCTS
Description
Features
The SK1925 is an extremely fast, stable, and accurate
low skew 1:9 clock / signal distributor featuring a
synchronous enable, which allows the outputs to be
turned off and on without the risk of an unpredictable
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.

SK1999
1:9 Signal Distribution
HIGH-PERFORMANCE PRODUCTS
Description
Features
•
1:9 Clock/Data Driver
•
•
•
3 GHz Fmax
The SK1999 is an extremely fast, stable, and accurate
low skew 1:9 clock / signal distributor featuring a
synchronous enable, which allows the outputs to be
turned off and on without the risk of an unpredictable
output pulse. The D - flip-flop is triggered on the falling
edge of the clock.
3.3V / 5.2V Compatible
Application note (AN 1001) for ease of
design-ins
Available in 32 pin, 5mm X5mm, TQFP
Package
•
The SK1999 has open collector (CML) outputs, targeted
for:
• Ultra high speed applications
• Adjustable common mode levels at the
destination.
