CS4385-CQZ

The CS4385-CQZ is an integrated channel chip consisting of an analog-to-digital converter (ADC) and a digital-to-analog converter (DAC). It is designed to offer high- performances, high-resolution and low power consumption while ensuring noise and distortion performance. The chip is commonly used in data acquisition, audio/video processing and communication systems and provides an ideal, low-cost replacement for standalone ADCs and DACs.

The primary application fields for the CS4385-CQZ include digital audio, digital video, medical imaging, mobile communications, and test equipment. It is well suited for applications which require the combination of analog and digital technologies, such as digital signal processing, audio processing, and data acquisition applications. Additionally, the chip is also used in home theater systems, automotive entertainment systems and professional music studios.

The CS4385-CQZ features several integrated features. It consists of two 8-/10/12-bit A/D and D/A converters, and is capable of 128-/196-/256-bit processing when used in conjunction with an external digital signal processor. It also provides on-chip processing functions such as phase balance, dynamic range control, a 32-bit timer, and 6th-order active-lowpass filter with a minima of 0.2 dB ripple. Additionally, the chip contains an internal voltage-controlled oscillator (VCO), a switched capacitor filter for DC offset cancellation, and an internal flexible timing estimator for bit-clock jitter tolerance. All these features combined make the CS4385-CQZ suitable for a variety of applications.

In terms of its working principle, the CS4385-CQZ comprises two interdependent and interacting data channels, which are used to process incoming signals. For the A/D converter, a cascade of high-speed pipeline A-D converters are employed to measure multiple bits of data in a single cycle, enabling high accuracy levels. The chip also employs high-speed, continuous time linearization (CTL) techniques to improve the accuracy, linearity and dynamic range of the ADC. On the other hand, the DAC uses multi-level pulse width modulation for improved noise performance and dynamic range.

In conclusion, the CS4385-CQZ is a high-performance integrated channel chip that provides an ideal solution for data acquisition, audio/video processing and communication systems. It features an array of integrated features such as a VCO, 8-/10-/12-bit A/D and D/A converters, and 6th-order active-lowpass filter for improved dynamic range and low-ripple. The chip also offers high-accuracy levels and low power consumption. The primary application fields for this chip include digital audio, medical imaging, mobile communications and test equipment.
