SNVSBA0D February 2020 – August 2021 LM61480-Q1 , LM61495-Q1 , LM62460-Q1
The LM6x4xx-Q1 SYNC/MODE pin can be used to synchronize the internal oscillator to an external clock. The internal oscillator can be synchronized by coupling a positive edge into the SYNC/MODE pin. The coupled edge voltage at the SYNC/MODE pin must exceed the SYNC amplitude threshold of VSYNCDH to trip the internal synchronization pulse detector. The minimum SYNC rising pulse and falling pulse durations must be longer than tPULSE_H and tPULSE_L respectively. The LM6x4xx-Q1 switching action can be synchronized to an external clock from 200 kHz to 2.2 MHz.
