Intel Pentium M Processor and Intel
Recommendations
Isolate from the 3.3 V power plane and use extra
decoupling.
®
Connect to the Intel P64H2 using a series
43 Ω ± 5% resistor.
No Connect.
®
Connect to the Intel ICH3-S using a series
43 Ω ± 5% resistor.
Connect to MCH using a series
43 Ω ± 5% resistor.
• Connect to the processor, MCH, or ITP
using a series 33 Ω ± 5% resistor, and
terminate to GND through a 49.9 Ω ± 1%
resistor.
• Unused Clock outputs: 10K Ω ± 5% pull-up
to VCC3.3.
No Connect.
475 Ω ± 1% pull-down to ground.
10 k Ω ± 5% pull-up to V3_CLK.
Connect to a series 33 Ω ± 5% resistor for
PCI33_CLK33, VIDEO_CLK33, FWH_CLK33,
SIO_CLK33, and LPC_CLK33.
No Connect.
Connect to a series 33 Ω ± 5% resistor for
ICH3_CLK33.
No Connect.
10 k Ω ± 5% pull-up to V3_CLK.
Connect to SLP_S3_N.
Connect to a series 22 Ω ± 5% resistor for CLK
14 output to LPC, VIDEO, SIO and ICH3-S.
10 k Ω ± 5% pull-down to ground.
10 k Ω ± 5% pull-down to ground.
Connect to the 3 V SMBus partition.
Connect to the Intel ICH3-S using a 33 Ω ± 5%
series resistor to ICH3_CLK48.
Terminate to V3_CLK_A.
