I tried to read and write registers, but had no success.
Then I am find the next information: After reset on SYNC_CLK pin, we must have some pulses. [CFR1<1> = 0 (default). The SYNC_CLK pin is active.] But I don't have any pulses on this pin.
Supply voltage is OK. Schematic is correct. On OSC/REFCLK pin -> 31.2 MHz / 600mV peak to peak.
This is my schematic:
I will be glad for the help.
