PRODUCT OVERVIEW
The PCM4104 is a high-performance, four-channel D/A
converter designed for professional audio systems. The
PCM4104 supports 16- to 24-bit linear PCM input data and
sampling frequencies up to 216kHz. The PCM4104
utilizes an 8x oversampling digital interpolation filter,
followed by a multi-level delta-sigma modulator with a
single pole switched capacitor output filter. This
architecture provides excellent dynamic and sonic
performance, as well as high tolerance to clock phase
jitter.

The PCM4104 incorporates a flexible audio serial port,
which accepts 16- to 24-bit PCM audio data in both
standard audio formats (Left Justified, Right Justified, and
Philips I
2
S) and TDM data formats. The TDM formats are
especially useful for interfacing to the synchronous serial
ports of digital signal processors. The TDM formats
support daisy-chaining of two PCM4104 devices on a
single three-wire serial interface (for sampling frequencies
up to 108kHz), forming a high-performance eight-channel
D/A conversion system.
The PCM4104 offers two modes for configuration control:
Software and Standalone. Software mode makes use of a
four-wire SPI port to access internal control registers,
allowing configuration of the full PCM4104 feature set.
Standalone mode offers a more limited subset of the
functions available in Software mode, while allowing for a
simplified pin-programmed configuration mode.
