Part Number: CDCI6214
CDCI6214, we design a product (customers need to add new functions to add clock function). We want to ask whether CDCI6214 has clock hold over function, that is, when the input clock is interrupted (or los), the output clock can still be maintained for a period of time, and when the clock restarts, it can glitchless normal work. As a result, I looked at TI's LMK04906/LMK0480X series all have this function. I wonder if CDCI6214 has similar function.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Alan O:
In reply to Jerry Hsueh:
The frequency increment and decrement pins should not be pulsed faster than 1 MHz, i.e. the minimum delay is 1 us between rising edges on GPIO1/GPIO4.
What is your end application and use case that requires dynamic clock frequency adjustment? What data protocol or interface do you intend to use this for, and what are the clock jitter requirements?
Our product is matrix display control board. The original application is shown in the figure (using CDCE937 to control VCO through PWM).
We intend to use the Frequency Increment and Decrement functions of CDCI6214 to control the clock instead of the original analog way to control VCO to achieve genlock.
Please help confirm whether CDCI6214 can be implemented.
What are the video interface (parallel or serial) and data rate?
What is the video clock jitter requirement? Clock frequency and signal type (differential or single ended)?
Do you prefer DCO frequency control via INC/DEC pin control or I2C control?
It should be, but maybe it is out of stock.
