BQ3285: What is the maximum capacitance of Xtal which can be used for BQ3285?

Part Number: BQ3285

 Hello guys,

 One of our customers is going to use BQ3285S-SB2(RTC, product going to EOL) because they have been using the device for many their products.

 They have the following questions for the device. Could you please give me your answers or comments?

Q1. What is the maximum capacitance value (Load capacitance) of Xtal which can be used for BQ3285? (Typical value is 6pF.)

Q2. They can prepare a Xtal which has 9pF load capacitance. Can it be used?

Q3. Can the following Xtal be used for BQ3285?

       DST310S (Load capacitance is 7pF version)

Q4. Can the following Xtal be used for BQ3285?

      FC-135R (Load capacitance is 7pF version)
