Description
O Master Clock Output Pin
EXT = “0”: System clock is output from PLL circuit (PLL mode),
EXT = “1”: Same frequency as MCKI is output (External mode)
- No Connect
Nothing should be connected externally to this pin.
- Digital Power Supply Pin, +2.7∼+5.5V
- Digital Ground Pin, 0V
I System Clock Input Pin
EXT = “0”: 27MHz (PLL mode), EXT = “1”: Other frequency (External mode)
I Serial Data Clock Pin
I Serial Data Input Pin
I Serial Input Channel Clock Pin
I Power-Down Pin
When “L”, the circuit is in power-down mode.
The AK4363 should always be reset upon power-up.
I Chip Select Pin at 3-wire Serial control mode
This pin should be connected to DVDD at I²C Bus control mode.
I Control Clock Pin at I²C bus control mode
I Control Clock Pin at 3-wire serial control mode
I/O Control Data Input/Output Pin at I²C Bus control mode
I Control Data Input Pin at 3-wire serial control mode
I Test pin
This pin should be connected to DVSS.
I Digital Input Level Select Pin
“L”: CMOS, “H”: TTL
I Control Mode Select Pin
“L”: 3-wire Serial, “H”: I²C Bus
I Chip Address Select 0 Pin
I Chip Address Select 1 Pin
O Rch Analog Output Pin
O Lch Analog Output Pin
O Common Voltage Output Pin, AVDD/2
Used for analog common voltage.
Large external capacitor is used to reduce power supply noise.
- Analog Ground Pin
- Analog Power Supply Pin
O Output Pin for Loop Filter of PLL Circuit
This pin should be connected to AVSS with one resister and one capacitor in series.
( See “SYSTEM DESIGN”.)
O Zero Input Detect Pin
When SDTI follows a total 8192 LRCK cycles with “0” input data or RSTN = “0”,
this pin goes to “H”.
Note: No input pins should be left floating.
