Fig.6 Application diagram for differential clock input (PECL-compatible) using a TTL to PECL translator.
If the clock lines are more than 1 inch long they must be matched. In fact, the 27
resistor will be changed
by the series connection of R1 and R2, with R1 = Z
o
placed close to pins CLK and CLK.
