ADIN1100_Clock input circuit

Category: Hardware
Product Number: ADIN1100

Hello

Please let me know your advice how to design clock input circuit of ADIN1100.

ADIN1100 destasheet P.37 says below

If the calculation formula is satisfied, is it acceptable to use values for C1 and C2 that differ from those in Table 28? 

For example , can we use below parameter  because of the availability of capacitors?

VCLK IN: 1.03V

VS:3.3V

Cstary:0

CPIN:3pF

C1:27pF

C2:56pF

Please let me know your advice.

  • Hi Teli,

    We recommend using the specified values of the capacitors for the ADIN1100 clock input circuit to ensure correct operation of the crystal oscillator. Using bigger capacitors may result in affected clock signal and/may overload the clock driver.
