DESCRIPTION  
Sampling Frequency: 10 kHz to 200 kHz  
The PCM1738 is a CMOS, monolithic, integrated  
circuit (IC) that includes stereo digital-to-analog  
converters (DACs) and support circuitry in a small  
SSOP-28 package. The data converters use a newly  
developed advanced segment DAC architecture to  
achieve excellent dynamic performance and  
improved tolerance to clock jitter. The PCM1738  
provides balanced current outputs, allowing the user  
to optimize analog performance externally, and  
accepts industry-standard audio data formats with  
16- to 24-bit data, providing easy interfacing to audio  
DSP and decoder chips. Sampling rates up to 200  
kHz are supported. The PCM1738 also has two  
optional modes of operation: an external digital filter  
mode (for use with the DF1704, DF1706, and  
PMD200), and a DSD decoder interface for SACD  
System Clock: 128, 192, 256, 384, 512, or 768
