DESCRIPTION
The PCM3000/3001 is a low cost single chip stereo
audio CODEC (analog-to-digital and digital-to-analog
converter) with single-ended analog voltage input and
output.
Both ADCs and DACs employ delta-sigma modula-
tion with 64X oversampling. The ADCs include a
digital decimation filter and the DACs include an 8X
oversampling digital interpolation filter. The DACs
also include digital attenuation, de-emphasis, infinite
zero detection and soft mute to form a complete
subsystem. The PCM3000/3001 operates with left-
justified, right-justified, I2S or DSP data formats.
PCM3000 can be programmed with a 3-wire serial
interface for special features and data formats.
PCM3001 can be pin-programmed for data formats.
Fabricated on a highly advanced CMOS process, the
PCM3000/3001 is suitable for a wide variety of cost-
sensitive consumer applications where good perfor-
mance is required. Applications include sampling key-
boards, digital mixers, mini-disc recorders, hard-disk
recorders, karaoke systems, DSP-based car stereo,
DAT recorders, and video conferencing.
