ak4671 AKM Semiconductor, Inc., ak4671 Datasheet - Page 25

• Manufacturer Part Number: ak4671
• Description: Stereo Codec With Mic/rcv/hp-amp
• Manufacturer: AKM Semiconductor, Inc.

Parameter
Control Interface Timing (4-wire Serial mode)
Control Interface Timing (I
Power-down & Reset Timing
Note 50. I
Note 51. CCLK should be input succeedingly until 10bit data of SAR ADC is read out at 4-wire serial mode
Note 52. CCLK rising edge must not occur at the same time as CSN edge.
Note 53. In case that SAR ADC data is read out via I
Note 54. Data must be held long enough to bridge the 300ns-transition time of SCL.
Note 55. The AK4671 can be reset by bringing PDN pin = “L” to “H” only upon power up.
Note 56. This is the count of LRCK “↑” from the PMADL or PMADR bit = “1” at PMSRB bit = “1”.
Note 57. The signal path is SDTI → SRC-A → SDTOA and PLLBT is locked.
Note 58. The signal path is SDTIA → SRC-B → SDTO.
