1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. The tolerances for this specification have been stated generically to enable the system designer to calculate 

the minimum and maximum values across the range of V

CC

.

3. GTLREF should be generated from V

CC

 by a voltage divider of 1% tolerance resistors or 1% tolerance 

matched resistors. Refer to the Mobile Intel

Platform Design Guide for implementation details.

4. R

TT

 is the on-die termination resistance measured at V

OL

 of the AGTL+ output driver. Refer to processor I/O 

buffer models for I/V characteristics.

5. COMP resistance must be provided on the system board with 1% tolerance resistors. See the Mobile Intel

All AGTL+ timings are referenced to GTLREF for both “0” and “1” logic levels unless otherwise 
specified.

The timings specified in this section should be used in conjunction with the I/O buffer models 
provided by Intel. These I/O buffer models, which include package information, are available for 
the Mobile Intel Pentium 4 Processor-M in IBIS format. AGTL+ layout guidelines are also
