description
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:
D Input clamp circuitry and a correlated double sampler (CDS)
D 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
D Two internal DACs for automatic or programmable optical-black-level and offset calibration
D 10-bit, 25-MSPS pipeline ADC for CCD mode and a 28-MSPS ADC for video mode
D Parallel data port for easy microprocessor interface and a serial port for configuring internal control registers
D Two additional DACs for external system control
D 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 –20°C to 75°C.
