The output displayed by the commands “clock reference show” and “clock config show” are values read from
PLL (ZL30143). For more information about these values, please refer to the PLL manual.
Enable clock signal to AMC input
The output buffers to the AMC clocks (CLK1 and CLK2) can be selected independently. The supported devices
are: 1=AMC1, 2=AMC2, 3=AMC3 …
The output signal frequencies of the PLL to source the AMC’s can be selected from the following predefined
values:
• 8khz
• 1544khz
• 2048khz
• 19440khz
# clicm clock output
Set clock output driver and select frequency
clock output <DEVICE> {clk1|clk2} {8khz|1544khz|2048khz|19440khz}
