Hi all,
Are there any recommended oscillator or operability confirmed oscillator for i.MX6 ?
My customer will use oscillator for 24MHz clock of i.MX6SL.
I read following threads but I could only get information on frequency deviation without the recommended circuit diagram.

Furthermore, this EB is mentioned only for crystal.

Please someone share the information about recommended oscillator or operability confirmed oscillator for i.MX6.

Hi Ko-hey
>Could you give us an opinion for it ?
I think Your considerations are correct. Sorry I have no other suggestion.
I think customer can add to this device level converter or try to find other device
with appropriate characteristics.
Best regards

Hi Ko-hey
one can try oscillator used in i.MX6UL EVK :
Buy NZ2520SH-24MHZ ERG3199A, Nihon Dempa Kogyo Co., Ltd. (NDK), ED Inventory

Hi igorpadykov,
Thank you for reply.
Where is it in i.MX6UL EVK ? I can't find it in following schematic.

hi, igorpadykov
Thank you for reply.
I understand EVK has 24MHz oscillator but I think it's not match for DC parameters of XTALI in i.MX6.
According to the datasheet of i.MX6, the XTALI high-level DC input voltage is from 0.8 x NVCC_PLL to NVCC_PLL V.
Furthermore, the nominal default setting as 1.1 V.
As a result, the XTALI high-level DC input voltage is from 0.88 to 1.1 V.
On the other hand, the specification of the device is as below..
Supply Voltage [VCC] (V) | +1.8 to +3.3 (*1) | |
VOL Max. / VOH Min. (V) | 0.1 VCC / 0.9 VCC | 0.2 VCC / 0.8 VCC |
https://www.ndk.com/en/products/search/clock/1190899_1433.html
Even if user select minimum supply voltage (Voh Min is 1.62 V), I think that it doesn't match the specification for i.MX6 XTALI.
Could you give us an opinion for it ?
