Intel® 3000 and 3010 Chipset Memory Controller Hub (MCH) Datasheet
Differential Host Clock In: These pins receive a differential host
clock from the external clock synthesizer. This clock is used by all of
the MCH logic that is in the Host clock domain. Memory domain clocks
are also derived from this source.
Differential PCI Express Clock In: These pins receive a differential
100 MHz Serial Reference Clock from the external clock synthesizer.
This clock is used to generate the clocks necessary for the support of
PCI Express.
Reset In: When asserted, this signal will asynchronously reset the
MCH logic. This signal is connected to the PCIRST# output of the ICH7.
All PCI Express output signals will also tri-state compatible to PCI
Express Specification Rev 1.0a.
This signal is 3.3V tolerant.
Power OK: When asserted, PWROK is an indication to the MCH that
core power has been stable for at least 10 μs.
External Thermal Sensor Input: This signal may connect to a
precision thermal sensor located on or near the DIMMs. If the system
temperature reaches a dangerously high value, then this signal can be
used to trigger the start of system thermal management. This signal is
activated when an increase in temperature causes a voltage to cross
some threshold in the sensor.
ICH Sync: This signal is connected to the MCH_SYNCH# signal on the
ICH7.
XOR Test: This signal is used for Bed of Nails testing by OEMs to
execute XOR Chain test.
All Z Test: This signal is used for Bed of Nails testing by OEMs to
execute ALL Z test.
Direct Media Interface: Receive differential pair (Rx)
Direct Media Interface: Transmit differential pair (Tx)
