System Clock: 128 f , 192 f , 256 f , 384 f  
S S S S  
Sampling Frequency: 5 kHz to 50 kHz  
The PCM1770 and PCM1771 devices are CMOS,  
monolithic, integrated circuits which include stereo  
digital-to-analog converters, headphone circuitry, and  
support circuitry in small TSSOP-16 and VQFN-20  
packages.  
Software Control (PCM1770):  
− 16-, 20-, 24-Bit Word Available  
− Left-, Right-Justified, and I S

− Slave/Master Selectable  
− Digital Attenuation: 0 dB to 62 dB,  
1 dB/Step  
− 44.1-kHz Digital De-Emphasis  
− Zero Cross Attenuation  
− Digital Soft Mute  
The data converters use TI’s enhanced multilevel -Σ  
architecture, which employs noise shaping and  
multilevel amplitude quantization to achieve excellent  
dynamic performance and improved tolerance to clock  
jitter. The PCM1770 and PCM1771 devices accept  
several industry standard audio data formats with 16- to  
− Monaural Analog-In With Mixing  
− Monaural Speaker Mode

24-bit data, left-justified, I S, etc., providing easy  
interfacing to audio DSP and decoder devices.  
Sampling rates up to 50 kHz are supported. A full set of  
user-programmable functions are accessible through a  
3-wire serial control port, which supports register write  
functions.
