Hi,

I would like to change 4MHz to 12MHz at Vcc=3.3V.

How should I choose external components?

Do you have any application notes?

Best Regards,

Kuramochi

Hello Kuramochi-san,

The SN74LV4046A is a direct replacement for the CD74HC4046A or CD4046B. There are two great application notes on using those devices that directly translate to the SN74LV4046A:

CMOS Phase-Locked-Loop Applications Using the CD54/74HC/HCT4046A and CD54/74HC/HCT7046A

Implementation of FSK Modulation and Demodulation using CD74HC4046A

You can also refer to the detailed information in the CD4046B and CD74HC4046A datasheets.

Please let me know if I can be of further assistance.
