TDA3MV: TDA3 Input Clock Frequency Issue

Tom Zhang

Part Number: TDA3MV

Tool/software:

HI,

We have designed a board with an RF input frequency of 50 MHz. Can it be used for the input clock of TDA3, and if so, can it be connected to OSC0 or OSC1? Must we use a crystal with a new frequency?

Thanks

Best Regards

Tom

Hi Tom,

I would recommend referring to TRM for checking input clock frequencies supported.

Is it true that OSC0 can only be 19.2 MHz, 20 MHz, or 27 MHz, and OSC1 can only be 19.2 MHz or 21 MHz?

Yes, that's correct and as given in the TRM.
