Pin Description
Crystal Connections (Input/Output) - I/O pins for an external crystal which may be used to generate the
master clock. See “Crystal Applications (XTI/XTO)” on page 24 or “Crystal Applications (XTI/XTO)” on
page 27.
Master Clock (Input/Output) -Clock source for the delta-sigma modulators. See “Crystal Applications
(XTI/XTO)” on page 24 or “Crystal Applications (XTI/XTO)” on page 27.
Left Right Clock (Input/Output) - Determines which channel, Left or Right, is currently active on the
serial audio data line.
Serial Clock (Input/Output) - Serial clock for the serial audio interface.
Serial Audio Data Output (Output) - Output for two’s complement serial audio data. This pin must be
pulled-up or pulled-down to select Master or Slave Mode. See “Master/Slave Mode” on page 24.
Serial Audio Data Input (Input) - Input for two’s complement serial audio data.
Digital Ground (Input) - Ground reference for the internal digital section.
Digital Power (Input) - Positive power for the internal digital section.
Logic Power (Input) - Positive power for the digital input/output interface.
Mode Select 0 (Input) - In conjunction with M1, selects operating mode. Functionality is described in the
Hardware Mode Speed Configuration table.
Mode Select 1 (Input) - In conjunction with M0, selects operating mode. Functionality is described in the
Hardware Mode Speed Configuration table.
Serial Audio Interface Select (Input) - Selects either the left-justified or I
Interface.
Reset (Input) - The device enters a low power mode when this pin is driven low.
Quiescent Voltage (Output) - Filter connection for internal quiescent reference voltage.
Quiescent Voltage (Input) - Connection for internal quiescent reference voltage.
Analog Input (Input) - The full scale input level is specified in the ADC Analog Characteristics specifica-
tion table.
Quiescent Voltage (Input) - Connection for internal quiescent reference voltage.
Analog Power (Input) - Positive power for the internal analog section.
Analog Ground (Input) - Ground reference for the internal analog section.
Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuits.
Channel A Mute Control (Output) - This pin is active during power-up initialization, reset, muting, when
master clock to left/right clock frequency ratio is incorrect, or power-down.
Differential Analog Audio Output (Output) - The full scale differential output level is specified in the
Analog Characteristics specification table.
Channel B Mute Control (Output) - This pin is active during power-up initialization, reset, muting, when
master clock to left/right clock frequency ratio is incorrect, or power-down.
