Other PLL Characteristics
The PLL VCOs oscillate continually from power-up. The PLL output dividers consistently
track the VCO, providing pulses to the clock trees. Logic that does not receive an
asynchronous reset can thus be reset “synchronously”.
A “locked” PLL will only serve to prove that the feedback loop is continuous. It will not
prove that the entire clock tree is continuous.
Analog Power Supply Pins
The Intel 5000X chipset MCH incorporates seven PLLs. Each PLL requires an Analog
Vcc and Analog Vss pad and external LC filter. Therefore, there will be external LC
filters for the Intel 5000X chipset MCH. IMPORTANT: The filter is NOT to be connected
to board Vss. The ground connection of the filter will be routed through the package
and grounded to on-die Vss.
I/O Interface Metastability
PCI Express can be operated frequency-locked to the core. Flits are fifteen-sixteenths
of the core frequency in 266 MHz mode, three-quarters of the core frequency in
333 MHz mode.
However, the phase between the frequency-locked domains is not controlled. This
scheme results in the possibility of a metastability resonance where, for example, the
commands generated by the core miss setup and hold to I/O every time. This condition
can be tolerated by carefully hardened metastability design.
Error List
This section provides a summary of errors detected by the Intel 5000X chipset . In the
following table, errors are listed by the unit / interfaces. Some units / interfaces may
provide additional error logging registers.
The following table provides the list of detected errors of a the MCH.
