AC Electrical Characteristics
VDDH = 3.0 to 3.6V, VDDL = 2.3 to 2.7V, VSS = 0V, TOPR = –40 to 85°C, fs = 44.1kHz unless otherwise noted.
When DSBCK and PLRCK clocks are supplied by external clock input, their frequencies are related to the
MCK input frequency by the following frequency divider ratios.
(DSBCK) cycle
= 8 × MCK cycle (64fs)
(PLRCK) cycle [4fs mode] = 128 × MCK cycle (4fs)
(PLRCK) cycle [2fs mode] = 256 × MCK cycle (2fs)
(PLRCK) cycle [fs mode] = 512 × MCK cycle (fs)
