DESCRIPTION
The PCM4104 is a high-performance, four-channel
digital-to-analog (D/A) converter designed for use in
professional audio applications. The PCM4104 supports
16- to 24-bit linear PCM input data, with sampling
frequencies up to 216kHz. The PCM4104 features lower
power consumption than most comparable stereo audio
D/A converters, making it ideal for use in high channel
count applications by lowering the overall power budget
required for the D/A conversion sub-system.
The PCM4104 features delta-sigma architecture,
employing a high-performance multi-level modulator
combined with a switched capacitor output filter. This
architecture yields lower out-of-band noise and a high
tolerance to system clock phase jitter. Differential voltage
outputs are provided for each channel and are well-suited
to high-performance audio applications. The differential
outputs are easily converted to a single-ended output
using an external op amp IC.
The PCM4104 includes a flexible audio serial port
interface, which supports standard and time division
multiplexed (TDM) formats. Support for TDM formats
simplifies interfacing to DSP serial ports, while supporting
a cascade connection for two PCM4104 devices. In
addition, the PCM4104 offers two configuration modes:
Standalone and Software-Controlled. The Standalone
mode provides dedicated control pins for configuring a
subset of the available PCM4104 functions, while
Software mode utilizes a serial peripheral interface (SPI)
port for accessing the complete feature set via internal
control registers.
The PCM4104 operates from a +5V analog power supply
and a +3.3V digital power supply. The digital I/O is
compatible with +3.3V logic families. The PCM4104 is
available in a TQFP-48 package.
