PRODUCTION DATA.
The FREQ/ SYNC pin can be used to synchronize the internal oscillator by an external clock. A positive voltage at the FREQ / SYNC pin must exceed the rising threshold (1.2 V) while must be lower than the falling threshold (0.4 V) to trip the internal synchronization pulse detector. The recommended frequency for the external clock is between 200 kHz and 2.2 MHz.
