DESCRIPTION

The PCM1780/81/82 is a CMOS, monolithic, inte-

grated circuit, which includes stereo digital-to-analog

converters and support circuitry in a small 16-lead

SSOP package. The data converters use TI’s en-

hanced multilevel delta-sigma architecture to achieve

excellent dynamic performance and improved toler-

ance to clock jitter. The PCM1780/81/82 accepts

industry standard audio data formats with 16- to

24-bit data, providing easy interfacing to audio DSP

and decoder chips. Sampling rates up to 200 kHz are

supported. The PCM1780/82 provides a full set of

user-programmable functions through a three-wire

serial control port, which supports register write

•

System Clock: 128 f_S, 192 f_S, 256 f_S, 384 f_S,

512 f_S, 768 f_S, 1152 f_SWith Autodetect

•

Software Control (PCM1780, PCM1782):

– Accepts 16-, 18-, 20-, and 24-Bit Audio Data

– Formats: Right-Justified, I²S, and

Left-Justified

– Digital Attenuation: Mode Selectable

• 0 dB to –63 dB, 0.5 dB/step

• 0 dB to –100 dB, 1 dB/step

– Digital De-Emphasis

functions. The PCM1781 provides

user-programmable functions through four control

pins.
