(2)-1-2. Set up XTI
Clock source of XTI of the AK4114 (U3) is selected by JP16 (XTI-TX) and JP17 (XTE-TX). When X’tal:
X2 is selected, and OBICK frequency and OLRCK frequency are changed, the value of X’tal: X2 should be
changed.
(a) XTI is supplied from X’tal: X2 (b) XTI is supplied from J4 (XTI-TX)
