Anything to ECL Receiver
HIGH-PERFORMANCE PRODUCTS
Description
ꢀeatures
The SK4436 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 SK4436 has 100Ω input termination resistors
across each of the four inputs to help reduce system
component count and increase integration.
