www.DataSheet4U.com VSP5000 SLES057 – DECEMBER 2002 12-BIT 30 MSPS DUAL CHANNEL CCD SIGNAL FRONT END FOR DIGITAL COPIER FEATURES D Dual Channel CCD Signal Processing: – – – – – – – – Correlated Double Sampler (CDS) Sample Hold Mode Digital Programmable Amplifier CCD Offset Correction (OB loop) 12-Bit Resolution INL: ±2 LSB DNL: ±0.5 LSB No Missing Codes APPLICATIONS D Copiers D Scanners D Facsimiles DESCRIPTION The VSP5000 device is a complete application specific standard product (ASSP) for charge-coupled device (CCD) line sensor applications such as copiers, scanners, and facsimiles. The VSP5000 device provides two independent channels of processing lines and performs analog front-end processing and analog-to-digital (A/D) conversion. Each channel has a correlated double sampler (CDS)/sample hold (SH) circuit, a 14-bit analog-to-digital converter (ADC), a digital programmable gain amplifier (DPGA), and an optical black (OB) correction loop. Data output is 12 bits in length and the 2-channel A/D data is multiplexed and output. The VSP5000 is available in a 64-lead LQFP package and operates from a single 3.3-V supply. D High Performance A/D: D High-Speed Operation – Sample Rate: 30 MHz (Minimum) D 78-dB Signal-To-Noise Ratio (at 0-dB Gain) D Low Power Consumption: – Low Voltage: 3 V to 3.6 V – Low Power: 290 mW (Typ) at 3.3 V – Standby Mode: 20 mW (Typ) Please be aware that an important notice concerning availability, standard warranty, and use in critical applications...
