CDCE72010 output to reference delay

Other Parts Discussed in Thread: CDCE72010

Hello,

How can I configure the CDCE72010 clock in order to have the same delay between the output clock and the reference clock after each power on. I've CDCE72010EVM with 10MHz reference input and 10MHz output and what I observe is that the phase difference between the output clock and the refence clock is different after each power on.

Best regards,

Hi Mateusz Walczak,

What you are looking for is a device with a 0-delay mode of operation that lines up the reference and output clock edges determininstically on every power up. CDCE72010 does not support 0-delay mode of operation. Please take a look at the LMK04800 family of parts.

0-delay single PLL mode is explained in Page 6 of the datasheet.
