JTAG
TCK is asynchronous to core clock. For private TAP register accesses, one TCK cycle is a
minimum of 10 core cycles. The TCK high time is a minimum of 5 core cycles in
duration. The TCK low time is a minimum of 5 core cycles in duration. The possibility of
metastability during private register access is mitigated by circuit design. A
metastability hardened synchronizer will guarantee an MTBF greater than 10
For public TAP register accesses, TCK operates independently of the core clock.
SMBus Clock
The SMBus clock is synchronized to the core clock. Data is driven into the Intel 5000P
Chipset with respect to the serial clock signal. Data received on the data signal with
respect to the clock signal will be synchronized to the core using a metastability
hardened synchronizer guaranteeing an MTBF greater than 10
can not be active until 10 mS after RESETI# deassertion. When inactive, the serial
clock should be deasserted (High). The serial clock frequency is 100 KHz.
GPIO Serial Bus Clock
The transmitted 100 Khz Virtual Pin Interface (VPI) clock (one of the SCL[4:0]’s) is
derived from the core clock. The PCI Express Hot-Plug signals reside on the Virtual Pin
Interface.
