NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies and cache sizes.
2. Not 100% tested. Specified by design characterization.
3. All source synchronous AC timings are referenced to their associated strobe at GTLREF. Source 
synchronous data signals are referenced to the falling edge of their associated data strobe. Source 
synchronous address signals are referenced to the rising and falling edge of their associated address strobe. 
All source synchronous AGTL+ signal timings are referenced to GTLREF at the processor core.
4. Unless otherwise noted these specifications apply to both data and address timings.
5. Valid delay timings for these signals are specified into the test circuit described in 
 and with GTLREF 
at 2/3

CC
 
± 2%.
6. Specification is for a minimum swing defined between AGTL+ V
IL_MAX
 to V
IH_MIN
. This assumes an edge rate 
of
 
0.3 V/ns to 4.0V /ns.
7. All source synchronous signals must meet the specified setup time to BCLK as well as the setup time to each 
respective strobe.
8. This specification represents the minimum time the data or address will be valid before its strobe. Refer to the 
Mobile Intel
 Pentium
 4 Processor-M and Intel
 
845MP/845MZ Chipset Platform Design Guide for more 
information on the definitions and use of these specifications.
9. This specification represents the minimum time the data or address will be valid after its strobe. Refer to the 
Mobile Intel
 Pentium
 4 Processor-M and Intel
 
845MP/845MZ Chipset Platform Design Guide for more 
information on the definitions and use of these specifications.
10.The rising edge of ADSTB# must come approximately 1/2 BCLK period (5 ns) after the falling edge of 
ADSTB#.
11. For this timing parameter, n = 1, 2, and 3 for the second, third, and last data strobes respectively.
12.The second data strobe (falling edge of DSTBn#) must come approximately 1/4 BCLK period (2.5 ns) after 
the first falling edge of DSTBp#. The third data strobe (falling edge of DSTBp#) must come approximately 2/4 
BCLK period (5 ns) after the first falling edge of DSTBp#. The last data strobe (falling edge of DSTBn#) must 
come approximately 3/4 BCLK period (7.5 ns) after the first falling edge of DSTBp#.
13.This specification applies only to DSTBN[3:0]# and is measured to the second falling edge of the strobe.
