DESCRIPTION
The PCM5310 is a four-channel/four-channel audio
codec with a 2-V_RMS driver, headphone amplifier,
analog multiplexer (mux), and six audio interface
ports for digital TV applications.
The PCM5310 accepts left-justified, right-justified,
and I²S audio data formats with 16 or 24 bits. The
PCM5310 also incorporates many functions through
the I²C interface, such as an analog bypass mode,
analog volume control, analog level control, analog
multiplexer, GPIO, zero flag, short protection,
de-emphasis filter, high-pass filter, and digital
attenuator. The six audio interface ports each have a
built-in digital mux and bypass functions to reduce the
need for additional DSP ports or other devices.
