Haswell Processor 2/7 ( CLK,MISC,JTAG )
Buffered reset to CPU
S3 circuit:- DRAM_RST# to memory
should be high during S3
CAD Note: Capacitor need to be placed
close to buffer output pin
TRACE WIDTH 10MIL, LENGTH <500MILS
Processor Pullups/Pull downs
If PROCHOT# is not used,
then it must be terminated
with a 56-ȍ +-5% pull-up
resistor to 1.05VS_VTT .
DDR3 Compensation Signals
S3 circuit:- DRAM PWR GOOD lCIRCUIT
PU/PD for JTAG signals
SSC CLOCK TERMINATION
STUFF R4R15 & R4R12
