Product Number: ADUCM350
We need to replace the 16 MHz crystal in an application based on ADuCM350.
The datasheet (Rev B, page 10) states that CEXT1 = CEXT2 should be between 10 and 15 pF.
The evaluation board (UG-668, Rev A, page 10) uses 2x 24 pF.
The HRM (UG-587, Rev E, page 456, table 640) states that no capacitors are required as these are integrated in the crystal (?)
The datasheet does not state the input capacitance of the HF_XTAL pins.
Please advise on how to proceed to define the load capacitors.
Thank you, enpa
