IDT Installation of the EB-LOGAN-19 Evaluation Board Power Sources Notes Power for the PES24NT24G2 and all downstream ports will be generated from the 12V from an external power connector. See Table 2.10. A 12V to 3.3V DC-DC converter will be used to provide power to five switching regulators to generate V CORE, V PEA, V...
IDT Installation of the EB-LOGAN-19 Evaluation Board Heatsink Requirement Notes The EB-LOGAN-19 evaluation board utilizes a heatsink with integrated fan. Reset The PES24NT24G2 supports two types of reset mechanisms as described in the PCI Express specifica- tion: – Fundamental Reset: This is a system-generated reset that propagates along the PCI Express tree through a single side-band signal PERST# which is connected to the Root Complex, the PES24NT24G2, and the endpoints.
IDT Installation of the EB-LOGAN-19 Evaluation Board SMBus Interfaces Notes The System Management Bus (SMBus) is a two-wire interface through which various system compo- nent chips can communicate. It is based on the principles of operation of I C. Implementation of the SMBus signals in the PCI Express connector is optional and may not be present on the host system.
IDT Installation of the EB-LOGAN-19 Evaluation Board SMBus Master Interface Notes Connected to the master SMBus interface are twenty-two 16-bit I/O Expanders (MAX7311AUG) and a serial EEPROM, U77 (24LC512). The I/O Expanders are used as the interface for the onboard hot-plug controllers (MIC2591B).
