Frequency Synchronization (SYNC/MODE)

Synchronize the internal oscillator of the TPSM63610 with a positive clock edge to SYNC/MODE, as shown in Figure 7-5. The synchronization frequency range is 200 kHz to 2.2 MHz.

TI recommends to tie a resistor from SYNC/MODE to either VCC or ground to keep the pin from floating if the sync signal is lost or off at start-up. A value in the 100-kΩ range. After a valid synchronization signal is applied for 2048 cycles, the clock frequency changes to that of the applied signal.

Referring to Figure 7-2, the voltage edge at the SYNC/MODE pin must exceed the SYNC amplitude threshold, VSYNCDH, of 1.8 V to trip the internal synchronization pulse detector. In addition, the minimum SYNC/MODE rising and falling pulse durations must be longer than the SYNC signal hold time, tSYNC_EDGE, of 100 ns.
