ASAHI KASEI
The following circuits are available to feed a clock into the XTI pin of AK4117.
1) X’tal mode
2) External clock mode
3) OFF mode
MS0157-E-03
Clock Source
The X’tal with proper value should be connected between XTI and XTO pins.
EXCK bit should be set to “1” and the proper frequency clock input into the XTI pin. XTO pin should be left open.
CM1-0 bits should be set to “00” and XTL1-0 bits to “11” respectively. XTI and XTO pins should be left open. The
XTI pin can also be connected to ground externally.
External Clock
Note: External capacitance depends on the crystal oscillator (Typ.10-40pF).
Figure 10. OFF mode (CM1-0= “00”, XTL1-0= “11”)
