•SATA link to the PCH
•Compliant to AMC.0, AMC.1 and AMC.3
•50W maximum power budget
As per AMC.1 R2.0, the carrier board is required to provide PCIe 100MHz reference clock to the AMC on FCLKA.
However, modules are not required to use it. Kontron recommends using AMC modules that use the reference
clock on FCLKA. If the module makes its own reference clock, then the spread spectrum of PCI-Express clock
synthetizer will be disabled by e-keying; otherwise the behavior of the PCI-Express link will be erratic.
The SATA interface on port 2 allows to use a SATA AMC storage mezzanine on the AT8060. AMC SATA electrical
path is properly designed for Hot Swap operation but special care must be taken to ensure proper un-mount
sequence within the operating system.
2.10 FPGA
The FPGA has many functions. One of them is to act as a companion chip to the IPMC. The states of all the
critical signals controlled by the IPMC are memorized in the FPGA and are preserved while the IPMC firmware
is being updated.
The FPGA is a RAM-based chip that is preloaded from a separate flash memory at power-up. Two such flash
memory devices are provided; one that can only be programmed in factory and the other one that can be
updated in the field. The factory flash is selected by inserting jumper JP2 pins 3-4. Field updates require to
cycle the power of the board. The IPMI LED2 will blink amber if the factory flash is being used to signal a fail
safe configuration.
The FPGA update complies to PICMG HPM.1 specification and is remotely updatable via any IPMC channel.
Note:
The thermal solution needs to be validated by the integrator when AMC Thermal Design power
exceeds 20W.
Note:
All electromagnetic compatibility testing has been done with spread spectrum. Disabling the spread
spectrum can complicate EMC.
