53 / 68 page [AK5554] 015099864-E-00 2016/03 - 53 - ■ Power Down Function/ Sequence The AK5554 enters power-down mode by setting the PDN pin to “L”. Digital filters are reset at the same time. [1] PCM Mode In slave mode, internal power down signal (Internal PDN) is released by inputting MCLK, BICK and LRCK after setting the PDN pin to “H”. In master mode, The Internal PDN is released by inputting MCLK after setting the PDN pin to “H”. Initialization cycle starts when the Internal PDN is released. The output data of SDTO will be valid in 583 x 1/fs after exiting power-down mode in slave mode, it will be valid in 578 x 1/fs after exiting power-down mode in master mode. During initialization, the ADC digital outputs of both channels are in 2 ’s complement format and forced to “0”. The ADC outputs settle to data correspondent to the input signals after the end of initialization. This settling takes approximately the group delay time.

Power-Up/Down Sequence Example Notes: (1) The PDN pin should be held to “L” for more than 150 ns after AVDD and TVDD are powered up. (2) a. LDOE pin = “H”, I2C pin = “H” and PSN pin = “H” (Parallel Mode): The internal LDO is powered up by releasing PDN pin to “H”. The Internal PDN is released by toggling MCLK for 16384times. b. LDOE pin = “H” and PSN pin = “L” (Register Mode): The internal LDO is powered up by releasing PDN pin to “H”. The internal PDN is released by toggling internal oscillator clock for 16384 times (max. 10 ms). c. LDOE pin = “L”: The internal PDN is released in 1 ms (max.) after releasing PDN pin to “H”. During this period, digital output and digital in/output pins may output an instantaneous pulse (max. 1 us). Therefore, referring the output of digital pins and data transmission with a device on the same 3-wire serial/I 2C bus as the AK5554 should be avoided in this period to prevent system errors. |
