Chapter 2 Installation of the EB48H12G2 Eval Board ® EB48H12G2 Installation Notes This chapter discusses the steps required to configure and install the EB48H12G2 evaluation board. All available DIP switches and jumper configurations are explained in detail. The primary installation steps are: 1.
IDT Installation of the EB48H12G2 Eval Board Notes The source for the onboard clock is the ICS841484 clock generator device (U10) connected to a 25MHz oscillator (X1). When using the onboard clock generator, the output frequency is fixed at 100MHz, therefore FSEL0 (S2, pin 2) should be in the ON position as the default setting.
IDT Installation of the EB48H12G2 Eval Board 2.5V I/O Voltage Regulator Notes This evaluation board can be stuffed to host the PES48H12G2 (PCIe Gen2) device or the PES48H12 (PCIe Gen1) device. Depending on which device is populated on the board, appropriate settings can be made.
