DESCRIPTION

The DSD1608 is a CMOS, monolithic, 8-channel

digital-to-analog converter which supports both PCM

audio data format and direct stream digital (DSD) audio

data format. The device includes an 8× digital

interpolation filter and a digital DSD filter with three

selectable frequency-response curves, followed by

Texas Instruments’ enhanced multilevel delta-sigma

modulator, which employs 4th-order noise shaping and

8-level amplitude quantization to achieve excellent

dynamic performance and improved tolerance to clock

jitter. Sampling rates up to 192 kHz for the PCM mode

and 64 × 44.1 kHz for the DSD mode are supported. A

full set of user-programmable functions is accessible

through a 4-wire serial control port, which supports

register write and read functions. The DSD1608

supports the time-division-multiplexed command and

audio data (TDMCA) format. The DSD1608 is available

in a 52-pin TQFP package.
