D F 1700 Dual Channel, 8x Oversampling DIGITAL FILTER Features - DUAL CHANNEL DIGITAL INTERPOLATION FILTERS - ACCEPTS 16-BIT INPUT DATA - USER-SELECTABLE FOR 16-,18-, OR 20- BIT OUTPUT DATA - SERIAL OUTPUT IS PATIBLE WITH PCM1700 AND PCM63 DACs - PASSBAND RIPPLE < 0.00005d B - STOPBAND ATTENUATION > 110d B - SINGLE +5V POWER SUPPLY FOR LOW POWER DISSIPATION OF 250m W Max - PLASTIC 28-PIN DIP AND 40-PIN SOIC PACKAGES DESCRIPTION The DF1700 is a high performance, 8x oversampling CMOS digital filter. This filter accepts 16-bit input data and is user-selectable for 16-, 18-, or 20-bit output data. The 8x oversampling feature converts the input data frequency (fs) to an output data frequency of 8 x fs by digital interpolation. By providing 8x oversampled data to an audio DAC, lower order analog filters can be used at the DAC's output, thus reducing filter phase non-linearities. Oversampling with the DF1700 simultaneously improves the fidelity of the analog reconstruction and reduces analog filter plexity at the output of the DAC. The DF1700 is available in a plastic 28-pin DIP and a 40-pin SOIC package, and is designed for patibility with the Burr-Brown PCM1700 and PCM63 digitaltoanalog converters.
