AC Electrical Characteristics
V_DD = 3.0 to 3.6V, V_SS = 0V, T_OPR = – 20 to 70°C, fs = 44.1kHz unless otherwise noted.
If DSBCKF, DSBCKB, F8WCK, F2LRCK clocks are input externally, by frequency division the clock input
on MCK has the following relationships.
(DSBCKF, DSBCKB) cycle = 8 × MCK cycle (64fs)
(F8WCK) cycle
= 64 × MCK cycle (8fs)
(F2LRCK) cycle
= 256 × MCK cycle (2fs)
