2CH, 12-Bit 30 Msps CCD Signal Processor For Copier
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.
