4.5.2.1. Mobile Intel Pentium 4 Processor–M AGTL+ I/O Buffer Compensation
For the Mobile Intel Pentium 4 Processor–M, the COMP[1:0] pins (see Figure 19) must each be pulled-
down to ground with 51.1 Ω ± 1% resistors and should be connected to the Mobile Intel Pentium 4
Processor–M processor with a Zo = 51.1 Ω trace that is less than 0.5 inches from the processor pins.
COMP[1:0] traces should be at least 25 mils (> 50 mils preferred) away from any other toggling signal.
