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. The DSD1702 is available in a 20-lead QSOP package. This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precaustions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
