Hi there, some questions about LM46002, could you please help have a look?
Suppose we use RT=80.6K to set a default Fs of 500KHZ. When power up, the IC works at 500khz . After some time delay, an external clock of 1MHZ is sent into SYNC pin, then IC will change to work at 1MHZ, which means the SNYC clock overrides the RT setting. If the external clock is turned off later, the IC will switch back to frequency set by RT .
Questions:
1. I think SYNC pin has a higher priority than RT setting. right?
2. What will happen during the frequency changing process? Will the output oscillate or be unstable?
3. If I get off the 80.6K RT resistor( let this RT pin float),the default Fs is still 500khz. Will the process still be the same as I wrote above ?
Thanks a lot :-)
