This pin is a logic input with quad-state input capability. The MODE pin is high when connected to VDD, low
when connected to DGND, and pulled up or pulled down through an external resistor and for the two mid-states
in order to distinguish the four input states. The pull-up or pull-down resistor must be 220 k
, ±5% in tolerance.
Note that the state of the MODE pin is only sampled by a power-on or a low-to-high transition of the RST pin.
When the MODE pin setting changes to change the operating mode, the new mode setting does not take effect
immediately; a RST pin toggle is required to make the new mode setting valid, and for the new mode to take
effect.
The OVF pin has two functions. It is primarily the flag for ADC overflow occurrence detection. It is also used to
indicate that the internal reset sequence is complete and that the device is ready to enter serial mode control.
The quality of SCKI may influence dynamic performance, because the PCM3168A and PCM3168A-Q1 (both the
ADC and DAC) operate based on SCKI. Therefore, it may be required to consider the jitter, duty, and rise/fall
time of the system clock.
In slave mode, the PCM3168A and PCM3168A-Q1 do not require a specific timing relationship between
BCKAD/LRCKAD and SCKI, and BCKDA/LRCKDA and SCKI; however, there is a possibility of performance
degradation with a certain timing relationship between them. In that case, specific timing relationship control
might resolve this performance degradation.
In master mode, there is a possibility of performance degradation because of heavy loads on BCKAD/LRCKAD,
BCKDA/LRCKDA, and DOUT1/2/3. It is recommended to load these pins as lightly as possible. Note that all
output clocks and signals go low; they do not go into a high-impedance state during power-save mode.
The PowerPAD of the PCM3168A and PCM3168A-Q1 is internally connected to the substrate of the silicon. It
should be connected to the ground plane with sufficient low conductance in electrical and thermal; see Figure 56.
The PowerPAD size is 7,25 mm x 7,00 mm (0,725 cm × 0.7 cm).
For power-down ON/OFF control without the pop-noise that is generated by a dc level change on the DAC
output, the external mute control is generally required. Use of the following control sequence is recommended:
external mute ON, codec power-down ON, SCKI stop and resume if necessary, codec power-down OFF, and
external mute OFF control.
