Hello,
I need to distribute a very accurate clock signal to a remote device (maximum distance: about 50 meters) using RS485 physical standard.
The recipient clock must feed an ADS131E04 ADC, so its frequency should be 2.048 MHz.
I see that very accurate oscillators on the market only have outputs over 10 MHz, hence my idea is to use a 16.384 MHz oscillator and then use a frequency divider (counter?) in order to take it to 2.048 MHz, which should be low enough to go through the 50 meters cable with no problems.
Now my question is: I want to divide my accurate clock by 8 without losing accuracy; what is the best way to do that?
Is a counter the best device for me? Or should I choose a PLL based device (I used CDCE706 in the past...)? Or something else?
Thanks in advance.
Regards,
Stefano
