HI,
i have difficultiesto find a proper crystl fot the CDCM61002
i tried to calculate the CL,A as descied in the datasheet's example and i failed.
please help me understand what are the parameters for the crystal

Hi Katz,
Sorry about that. What frequency crystal are you trying to acquire for your application? I will be happy to suggest options based on your frequency needs.

Hi Yoav,
All parameters except for CL are OK for the Abracon crystal that you selected. The recommend CL is 8pF typical (10pF Max). ABM3-24.000MHz-B2-T load capacitance is 18pF.
Some 8pF options are:
AVX
The ESR Max spec for these crystal is 60 ohms but that should be OK.

Hi Arvind and tanks for the fast replay.
I know that the crystal's load capacitance is 18pF but i want to note that the rest properties are as follow:
1. motional capacitance is about 9.86fF
2. ESR is about 8.88 ohm
3. shunt capacitane is 2.91pF
Now, can you explain me how to use equation 2 in the dataheet?
this equation should help me to determine the actual load capacitance in the PCB.
thanks
and best regards
Yoav
