CY27410 crystal

[Yas99]

Hello.

Can I use this crystal for CY27410 ?

P/N: ECS-250-10-36B-CTN-TR

* ECS Inc., ECX-2236B series ( https://ecsxtal.com/ecx-2236b )
* Frequency: 25MHz
* Load Capacitance: 10pF(Specify in P/N)

Hi @Yas99,

According to the crystal specifications mentioned in the datasheet, the crystal is not satisfying the max Co limit. As per the CL, Co should be 2 pF, but the crystal's Co is 3 pF.

Please find a different crystal with Co (max) 2 pF (and other specifications remain the same).

Thanks,

Ritwick

Hi,Ritwick,

Thank you for your answer.
Do you have a recommended crystal ?

Some manufacturers do not put Co in the datasheet..

Hi @Yas99,

Our CY3679 EVK uses the below crystal. You may use that crystal.

Hi,Ritwick,

Thank you for your answer.
But manufacturer do not put Co in datasheet.
(Is Co specifyied optional P/N ?)

I searched for an alternative crystal.
Can I use this crystal for CY27410 ?

* ECS Inc., ECX-2236B2 series ( https://ecsxtal.com/ecx-2236b2 )
* Frequency: 32MHz (instead of 25MHz)
* Equivalent Series Resistance: 40ohm Max
* Drive Level: 100uW Max
* Load Capacitance: 12pF(Specify in P/N)
* Shunt Capacitance: 3pF

Hi @Yas99,

I know for that crystal, Co is not mentioned in the datasheet, but it's been working fine on our EVK. That's why I asked you to look for that option. However, ECS-320-12-36B2-CKY-TR crystal looks okay to me.

Thanks,

Hi Ritwick,

Thank you for your answer.
My question has been cleared.

I will try ECS-320-12-36B2-CKY-TR.
