ak7753 AKM Semiconductor, Inc., ak7753 Datasheet - Page 14

• Manufacturer Part Number: ak7753
• Description: Audio/hands Free Dsp With Stereo Codec
• Manufacturer: AKM Semiconductor, Inc.

2) Reset
Note 32. The AK7753 can be powered up when INIT_RESET_N pin = “L”. The power supply must be ON and the
master clock must be input before the INIT_RESET_N pin transitions “H”.
3) Audio interface
Note 33. BITCLK_I “↑“ must not occur at the same time as SYNC_I edge.
Note 34. BITCLK_O “↑“ must not occur at the same time as SYNC_O edge.
(When control register SEL_BCK bit = “0”. The edge reverses when SEL_BCK bit = “1”.)
