need to be set 10% slower than the sync frequency. This circuit is also
used in Voltage Mode operation for master/slave operation. The clock
signal would be coming from the master which is set at the desired
operating frequency, while the slave is set 10% slower.

The sync pulse fed into the clock pin must be at least 3.9 V. R
