Part Number: CDC5801A
Other Parts Discussed in Thread: CDCM1802, CDCL1810, LMK01000, CDCL1810A

For our new project I’m searching for the chip with clock division ratio = 4.

Input frequency is 99 MHz .

Also, this divider need to have low jitter.

I found CDC5801A chip but datasheet provides some kind gaps in the in/out frequency ranges.

For example Table 2 .

Maybe you can recommend another chip for this application?

Thank you.

I suggest CDCM1802 as a low-jitter buffer with programmable divide ratios (/1, /2, /4, /8) and supports differential or single-ended clock signaling on the input and output paths.

You may also refer to our part selector with clock buffer with dividers:

We have some other clock dividers that may fit your needs. Please take a look at our offering here:

I recommend looking into LMK01000 and CDCL1810 for low additive jitter.
The LMK010x0 family are low-jitter has 8 outputs (combination of LVDS and LVPECL) with programmable dividers.
The CDCL1810 / CDCL1810A are low-jitter clock dividers that have 10 outputs with output divider selection.

Kind regards,
Lane
