PRODUCT OVERVIEW
The PCM4108 is a high-performance, eight-channel D/A
converter designed for professional audio systems. The
PCM4108 supports 16- to 24-bit linear PCM input data and
sampling frequencies up to 216kHz. The PCM4108
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. Functional block diagrams in Figure 1 and Figure 2
illustrate Standalone and Software modes, respectively.
The PCM4108 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 PCM4108 offers two modes for configuration control:
Software and Standalone. Software mode makes use of a
five-wire SPI port to access internal control registers,
allowing configuration of the full PCM4108 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.
