DS4201 Datasheet, PDF (12/24 Pages) Dallas Semiconductor – USB Audio DAC

DS4201
For crystals, use parallel resonant, fundamental mode with a CL specification between 10 pF and 20 pF at
the required frequency. Parallel loading capacitors with a value of approximately twice CL are also
required. The connection scheme shown in APPENDIX C should be used.
For external CMOS crystal oscillators, make a connection directly to the DS4201 X1I and/or X2I inputs.
The X1O and X2O outputs must be left floating for this arrangement.
