Non-inputted detection
When existence of the edge of the input signal from RX terminal is detected and there is no fixed
time edge, VCO oscillation operates by free run. Since VCO oscillation frequency and CKO terminal
output are set to about 80 MHz, please change it to an external clock automatically by the internal
program at the time of less inputting, or choose XI input by setup of command register.

6)
Miss lock detection
By comparing the input signal and the oscillation frequency from RX terminal, a Miss lock is
detected and the signal for escaping from a miss lock is outputted from FCONT terminal.

DSP Part Clock Generating Circuit
It is the circuit which generates a clock required in order to operate a decode program. DLL circuit can
generate the DLL clock of a crystal oscillation clock.
DLL circuit and a crystal oscillation circuit block are shown in Figure 20.
