■
16MHz or 24 MHz crystal resonator can be used as the master clock. If the CKM pin is set to “H”, the AK5373 supports
24MHz. If the CKM pin is set to “L”, the AK5373 supports 16MHz. The AK5373 can drive the clock up to three external
loads. The AK5373 generates 48MHz for system clock from 16MHz or 24MHz by system PLL circuit.
The clock for the MCKI/XTI pin can be generated by the following methods:
1) X’tal (XTE pin = “H”)
2) External clock (XTE pin = “L”)
