Analog positive power supply

Analog negative power supply

Buzzer output, a pulse-density modulated signal to apply to external buzzer driver

Digital positive power supply

Digital negative power supply

Earphone 1 amplifier output (−)

Earphone 1 amplifier output (+)

Earphone 2 amplifier output

Analog positive power supply for the earphone amplifiers

Analog negative power supply for the earphone amplifiers

Microphone bias supply output, no decoupling capacitors

Master system clock input (2.048 MHz) (digital)

MIC1 input (+)

MIC1 input (−)

MIC2 input (+)

MIC2 input (−)

Receive PCM input

Transmit PCM output

PCM frame synchronization

PCM data clock

PLL negative power supply

PLL digital power supply

Selects the power-up default mode

Internal reference current setting terminal—use precision 100

-

kΩ resistor and no filtering capacitors

Active low reset

I2C-bus serial clock—this input is used to synchronize the data transfer from and to the PCM codec

I2C-bus serial address/data input/output—this is a bidirectional terminal used to transfer register

control addresses and data into and out of the CODEC. It is an open

-

drain terminal and therefore

requires a pullup resistor to VDD (typical 10 kΩ for 100 kHz)

Ground return for bandgap internal reference
