Description
The CS5317 is an ideal analog front-end for voiceband signal processing applications such as high-performance modems, passive sonar, and voice recognition systems. It includes a 16-bit A/D converter with an internal track & hold amplifier, a voltage reference, and a linear-phase digital filter.
An on-chip phase-lock loop (PLL) circuit simplifies the CS5317’s use in applications where the output word rate must be locked to an external sampling signal.
The CS5317 uses delta-sigma modulation to achieve 16-bit output word rates up to 20 kHz. The .
