6.4.2 Pericom PI6C20400 1-to-4 Differential Clock Driver

Pericom Semiconductor's PI6C20400 is a high-speed, low-noise differential clock driver/buffer compatible

with CML and HCSL differential I/O technology.

The device distributes a differential input clock to four differential pairs of clock outputs either with or

without PLL. The clock outputs are controlled by input selection of several static control signals and Host

SMBus interface. The device oriented and designed for PCI Express applications.

6.4.3 SPI NOR Flash

The 82574L requires non-volatile memory content for initialization and configuration. The NVM is

connected to a single Serial Peripheral Interface (SPI). The 82574L is compatible with many sizes of 4-wire

SPI NVM devices. The required NVM size is dependent upon system requirements. FM-XTDE4U2/4 NVM

is implemented with Winbond W25Q80BL 8Mbit Flash memory.
