About Oscillator specification in i.MX6DQ.

Dear All,

 

Hello. The XTALI Vih spec is below from IMX6DQAEC(Rev.4).

XTALI high-level DC input voltage (Vih) : 0.8 x NVCC_PLL_OUT [Min]

 

But, the current customer's system was below.

- NVCC_PLL_OUT: 1.1V

- VIH: 0.87V  --> (= 0.79 x NVCC_PLL_OUT)

 

My customer must remove the 2.2 M-ohm resistor to meet the DC spec.

On the one hand, the 2.2 M-ohm resistor must need for ERR005777 in Chip errata.

 

[Question]

Is it possible to be permissible the VIH (=0.87V) in MX6DQ?

(Oscillator maker answered that matching is OK and 2.2M-ohm shouldn't be removed for ERR005777.)

 

Best Regards,

Keita
