Description

O Master Clock Output Pin

Same frequency as MCKI is output

O Transmit Channel Output Pin

- Digital Power Supply Pin, +2.7∼+5.5V

- Digital Ground Pin, 0V

I Master Clock Input Pin

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 AK4353 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 DVDD.

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

- No Connect

Nothing should be connected externally to this pin.

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.
