APPLICATION OF SYNCHRONIZATION
1. The unit is capable of external synchronization from an independent
time base with a switching rate between 200kHz and 215kHz
2. The amplitude of the synchronizing pulse train is TTL compatible
3. The duty cycle of the CLK should be 20% high and 80% low
4. Synchronization is referenced to negative input (-Vin)
