3V, 10-Bit, 25 MSPS, Area CCD Analog Front End
The VSP1021 device is a highly-integrated monolithic analog-signal processor/digitizer designed to Interface the area charge-coupled-device (CCD) Sensors in digital-camera and camcorder applications. The VSP1021 device performs all the Analog processing functions necessary to maximize the dynamic range, corrects various errors associated with the CCD Sensor and then digitizes the results with an on-chip, high-speed ADC The key components of the VSP1021 device include: Input clamp circuitry and a correlated double sampler (CDS) Programmable-gain Amplifier (PGA) with 0-dB to 36-dB gain range for CCD mode and 0-dB to 12-dB range for Video mode Two internal DACs for Automatic or programmable optical-black-level and offset calibration 10-bit, 25-MSPS pipeline ADC for CCD mode and a 28-MSPS ADC for Video mode Parallel data port for easy Microprocessor Interface and a serial port for configuring internal control Registers Two additional DACs for external system control Internal reference voltages
The VSP1021 device is designed using advanced CMOS process and operates from a single 3-V power supply with a normal power consumption of just 95 mW, and 1 mW in power-down mode.
High throughput rate, single 3-V operation, very-low-power consumption, and fully-integrated analog-processing circuitry make the VSP1021 device an ideal CCD and video-signal-processing solution for electronic video-camcorder applications.
This device is available in a 48-terminal TQFP package and is specified over an operating temperature range of ?20C to 75C.
