CS5317 is a 16-bit, 20 kHz oversampling A/D converter from Cirrus Logic that provides a complete voiceband DSP front-end, including a 16-bit A/D converter, internal track-and-hold amplifier, on-chip voltage reference, linear-phase digital filter, and on-chip phase-lock loop (PLL) for simplified output phase locking in modem applications. The CS5317 features DSP-compatible serial interface and offers output word rates up to 20 kHz. It is also characterized by low power dissipation (220 mW).
The CS5317 is a 16-bit, 20 kHz oversampling analog-to-digital converter designed for voiceband signal processing applications such as high-performance modems, passive sonar, and voice recognition systems. It integrates a complete voiceband DSP front-end, including a 16-bit A/D converter, an internal track & hold amplifier, an on-chip voltage reference, and a linear-phase digital filter.
The device utilizes delta-sigma modulation to achieve 84 dB dynamic range and 80 dB total harmonic distortion. It features an on-chip phase-lock loop (PLL) to simplify output phase locking in modem applications and offers a DSP-compatible serial interface. The CS5317 operates with low power dissipation of 220 mW and supports output word rates up to 20 kHz.
