Package
The SK4430 is an extremely fast, stable and accurate
low skew quad buffer or cable driver / receiver. It can
asychronously pass four distinct signals, or it can
resynchronize them to a common clock. In addition, all
four outputs may be asynchronously enabled or
disabled. All of the D flip-flops are triggered on the
rising edge of the CLK input. It is also capable of
receiving inputs of any technology or voltage level.

Application Notes
The SK4430 uses 50Ω outputs with sink/source
capability, and is optimized for applications that require:
• Point to point, double terminated, timing
critical lines
AN1001 - EPIC Family Product Line
AN1003 - Termination Techniques for ECL / LVECL
PECL / LVPECL Devices
AN1004 - Interfacing Between LVDS and ECL /
LVECL / PECL / LVPECL
• Point to point, series terminated, timing
critical lines
