C is a registered trademark of Philips Semiconductors.
Note 51. CCLK should be input succeedingly until 10bit data of SAR ADC is read out at 4-wire serial mode (
Figure 97
).
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
2
C bus, SCL should be input succeedingly corresponding 2 byte data
including ACK (
Figure 104
).
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.
