DSD1702 描述
The DSD1702 is a CMOS, monolithic, stereo digital-to-analog converter that supports both PCM audio data format and direct stream digital (DSD) audio data format.
The device includes an 8x digital interpolation filter for PCM signals. A digital DSD filter provides three different selectable frequency response options, followed by Burr-Brown’s enhanced multilevel delta-sigma modulator employing 4th-order noise shaping and 8-level amplitude quantization. This design achieves excellent dynamic performance and improved tolerance to clock jitter.
DSD1702 sampling rates of up to 192 kHz for PCM mode and 44.1 kHz × 64 for DSD mode are supported. A full set of user-programmable functions is accessible through a 3-wire serial control port, supporting register write functions.
