3. PCI-EK01 Board Explanation
It simply explains about board functions. Refer to a "Specification part" regarding a detailed function.
3.1 PCI-EK01 Function
USER I/O
Figure 3-1 shows that the PCI-EK01 has a lot of functions for various test. Each configuration
function is as follows.
(1) Core Control
The PCI-EK01 composes a PCI Target, external ADC, DAC interface and FIFO/TIMER/Counter
with using a FPGA (Spartan3). It is not used a UART function, it will be upgrade later.
(2) Level Shifter
A Level shifter exchanges a logic level of PCI to a logic level of FPGA. So, it is handily usable
just place to a slot without jumper setup of PCI 3.3V system or PCI 5V bus system.
(3) Power Distribution
It gets from 5V power at PCI bus and it supply as making the necessary 1.2V, 2.5V, 3V, 3.3V
power to use at board.
