These devices differ in the serial interface format used for audio data input. The CS4334 family is based on delta-sigma modulation, where the modulator output controls the reference voltage input to an ultra-linear analog low-pass filter. This architecture allows for infinite adjustment of sample rate between 2 kHz and 100 kHz simply by changing the master clock frequency. The CS4334 family contains on-chip digital de-emphasis, operates from a single +5 V power supply, and requires minimal support circuitry. These features are ideal for portable CD players and other portable playback systems. PI248PP1 APR `98 1 PI4334.FM Page 2 Friday, April 24, 1998 11:10 AM CS4334/5/6/7/8/9 Overview DEM/SCLK 2 LRCK SDATA 3 1 Serial Input Interface De-emphasis AGND 6 VA+ 7 Voltage Reference Interpolator Modulator DAC Analog Low-Pass Filter 8 AOUTL Interpolator Modulator 4 MCLK DAC Analog Low-Pass Filter 5 AOUTR Overview The CS4334 family of devices offers a complete stereo digital-to-analog system including digital interpolation, fourth-order delta-sigma digital-to-analog conversion, digital de-emphasis and analog filtering. This architecture provides a high tolerance to clock jitter. The primary purpose of using delta-sigma modulation techniques is to avoid the limitations of laser trimmed resistive digital-to-analog converter architectures by using an inherently linear 1-bit digital-to-analog converter. The advantages of a 1-bit digital-to-analog converter include: ideal differential linearity, no distortion mechanisms due to resistor matching errors and no linearity drift over time and temperature due to variations in resistor values. The CS4334 family of devices supports two modes of operation. The devices operate in Base Rate Mode (BRM) when MCLK/LRCK is 256, 384 or 512 and in High Rate Mode (HRM) when MCLK/LRCK is 128 or 192. High Rate Mode allows input sample rates up to 100 kHz. 2 PI248PP1 APR `98 PI4334.FM Page 3 Friday, April 24, 1998 11:10 AM CS4334/5/6/7/8/9 FAQs FAQs 1) A: 2) A: What competitive advantages do these D/A converters offer? These DACs provide the smallest and most cost-effective solution for CD quality digital audio. What is the difference between High Rate Mode (HRM) and Base Rate Mode (BRM)? These DACs support two oversampling modes. 128x oversampling, BRM, is used for sample rates less than 50 kHz and 64x oversampling, HRM, is used for sample rates greater than 50 kHz. Therefore a 12.288 MHz MCLK can support both 48 kHz and 96 kHz sample rates. Are the CS4334, CS4338, and CS4339 drop-in replacements for the CS4331, CS4333, and CS4330 respectively? The CS4334, CS4338, and CS4339 are functionally compatible and have the same pin-out as the CS4331, CS4333, and CS4330 respectively, but are in a smaller package. The new DACs are in an 8-pin 150 mil wide Jedec SOIC package. The CS4330/1/3 are in an 8-pin, 208 mil wide EIAJ SOIC package. 3) A: PI248PP1 APR `98 3 PI4334.FM Page 4 Friday, April 24, 1998 11:10 AM CS4334/5/6/7/8/9 Ordering Information Ordering Information Model CS4334-KS CS4335-KS CS4336-KS CS4337-KS CS4338-KS CS4339-KS Temperature -10 to +70C -10 to +70C -10 to +70C -10 to +70C -10 to +70C -10 to +70C Package 8-pin Plastic SOIC 8-pin Plastic SOIC 8-pin Plastic SOIC 8-pin Plastic SOIC 8-pin Plastic SOIC 8-pin Plastic SOIC Serial Interface 16 to 24-bit, I2S 16 to 24-bit, left justified 24-bit, right justified 20-bit, right justified 16-bit, right justified 18-bit, right justified, 32 Fs Internal SCLK mode Functional Compatibility CS4330-KS CS4339-KS CS4331-KS CS4334-KS CS4333-KS CS4338-KS For further information on Crystal products, please visit our website "www.crystal.com" or call our literature department (800) 888-5016 ext. 3594 or (512) 912-3594 for data sheets and application notes. 4 PI248PP1 APR `98 PI4334.FM Page 5 Friday, April 24, 1998 11:10 AM Sales Office and Applications Support UNITED STATES Western Area Cirrus Logic, Inc. 3100 West Warren Ave. Fremont, CA 94538 Ph: 510-623-8300 FAX: 510-252-6020 Southern California, Sales Westlake Village The Townsgate Executive Bldg. 2659 Townsgate Road, Suite 238 Westlake Village, CA 91361 Ph: 805-371-5860 FAX 805-371-5861 Cirrus Logic, Inc. 6650 S.W.
