Data output
P
I/O - output state is controlled by combinations of RSTN/PDN/OE pin settings (note 1)
- this pin is used as an I/O pin in test mode
P
O
Data output pin ( LSB )
- output state is controlled by combinations of RSTN/PDN/OE pin settings (note 1)
No connection – leave floating
- Reserved for AKM testing
No connection – leave floating
- Reserved for AKM testing
P
I ^{Test mode 1}
- connect this pin to DVSS (internally pulled-down)
Data clock for output interface
P
I/O ^{- output state is separately controlled by combinations of RSTN/PDN/OE pin}
settings (note 1)
- this pin is used as an I/O pin in test mode
I²C data
P
I/O
- this pin is pulled-up to PVDD
- Hi-Z input is allowed when PDN is low
- SDA input is not accepted during reset operation
Power supply for interface
P
P - interface power supply for DTCLK, OE, PDN, RSTN, DATA[7:0], HD/HV,
VD/VAF/FIELD, NSIG, DVALID, SDA, SCL.
I²C clock input
P
I
- an input level below PVDD should be input
- Hi-Z input is allowed when PDN is low
- SCL input is not accepted during reset operation
Output enable
P
I
- L : digital output pins are at high-Z
- H : data is available for output
- Hi-Z input on OE pin is prohibited
Reset signal input
- Hi-Z input to this pin is prohibited
P
I _{- L: reset}
- H: normal operation
D
P Digital power supply
Power-down control
P
I
- Hi-Z input to this pin is prohibited
- L: power-down
- H: normal operation
P
I ^{Test mode 0}
- connect this pin to DVSS (internally pulled-down)
No connection – leave floating
- Reserved for AKM testing
No connection – leave floating

Quartz crystal oscillator connection (tie to digital ground via a 22pF capacitor)
- 27.00 MHz crystal oscillator should be used.
D
O - this pin outputs DVSS level when PDN = L.
- when a crystal oscillator is not used, this pin can either be left open (NC) or
connected to DVSS
D
G Digital ground pins
D
I
Quartz crystal oscillator connection (tie to digital ground via a 22pF capacitor)
- 27.00 MHz crystal oscillator should be used
