VCC (CORE)
Decoupling
•
Recommended bulk decoupling:
•
(4) 220 µF SP caps - ESR 12 m
Ω
(max) and
ESL 3.5 µH, placed near CPU north power
corridor (pin map row AF).
•
Recommended mid-frequency decoupling:
•
(35) 10 µF 0805 caps - ESR 5 m
Ω
(typ) and
ESL 0.6 nH placed in and near package
outline.
•
Sharing of vias between several VCC-CORE
pins or ground pins is not allowed.
•
It is highly recommended that
decoupling guidelines detailed in
be followed for
efficient VRM performance.
VCCP
Decoupling
•
Recommended bulk decoupling:
•
(2) 150 µF POSCAP - ESR 42 m
Ω
(typ) and
ESL 2.5 nH, placed one each near the CPU
and the GMCH packages.
•
(10) 0.1 µF X7R 0603 caps - ESR 16 m
Ω
(typ) and ESL 0.6 nH, placed on the
secondary side within the CPU package
outline.
•
Refer to
for
processor VCCP decoupling
recommendations.
NOTES:
1. A[31:3]# pins on the processor correspond to HA[31:3]# pins on the GMCH.
2. ADSTB[1:0]# pins on the processor correspond to HADSTB[1:0]# pins on the GMCH.
3. DSTBN[3:0]# pins on the processor correspond to HDSTBN[3:0]# pins on the GMCH.
4. DSTBP[3:0]# pins on the processor correspond to HDSTBP[3:0]# pins on the GMCH.
5. D[63:0]# pins on the processor correspond to HD[63:0]# pins on the GMCH.
6. REQ[4:0]# pins on the processor correspond to HREQ[4:0]# pins on the GMCH.
7. The RESET# pin on the processor corresponds to the CPURST# pin on the GMCH. Refer to the ITP
and
for treatment of RESET# when using
ITP700FLEX debug port.
8. The TRDY# pin on the processor corresponds to the HTRDY# pin on the GMCH.
