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)
