About CLKx_N voltage range in i.MX6DQ.

[keitanagashima]

Dear Sir or Madam,

Hello.

Refer to Table 2-7. Oscillator and clock recommendations in Hardware Development Guide for i.MX 6, Rev. 1.

There is below description.

======

Alternatively, a single-ended signal can be used to

drive a CLKx_P input. In this case, the corresponding

CLKx_N input should be tied to a constant voltage

level equal to 50% of VDD_HIGH_CAP.

======

How much is the deviation of the CLKx_N voltage permissible?

Do you have voltage range of CLKx_N?

Best Regards,

Keita

Hi Keita

TIA/EIA-644 standard.sect.4.2.4

defines allowable common voltage range as

+0.050 V to +2.350 V . So this voltage can be applied

to CLKx_N.

Best regards

igor
