Functionality description

Under normal operation (function) conditions the signal synchronized by reference

voltage source (from pin 12) having passed the controller of data transmission delay (see

fig.1) and transformed by external electrical circuit returns into the IC. Then, logic input (pin

11) enables to choose whether synchronization signal (from clock synchronization input –
