Intel Arria 10 FPGA User Manual

4.4.12. The Clock Control
The Clock Control application set the three programmable oscillators to any frequency
between 10 MHz and 810 MHz. The frequencies support eight digits of precision to the
right of the decimal point.
The Clock Control communicates with the MAX V device on the board through the
JTAG bus. The programmable oscillators are connected to the MAX V device through a
2-wire serial bus.

Control Description
Serial Port Registers Shows the current values from the Si570 registers for frequency configuration.
Target frequency (MHZ) Allows you to specify the frequency of the clock. Legal values are between 10
and 810 MHz with eight digits of precision to the right of the decimal point. For
example, 421.31259873 is possible within 100 parts per million (ppm). The
Target frequency control works in conjunction with the Set New Freq control.
