6.4.9. The Clock Control

The Clock Control application sets the Si570 programmable oscillators to any frequency between 10 MHz and 945 MHz and select frequencies to 1400 MHz. The oscillator drives a 2-to-6 buffer that drives a copy of the clock to all transceiver blocks of the FPGA.

The Clock Control application runs as a stand-alone application. ClockControl.exe resides in the <package dir>\examples\board_test_system directory.

The Clock Control communicates with the MAX V device on the board through the JTAG bus. The Si570 programmable oscillator is connected to the MAX V device through a 2-wire serial bus.
