FEATURES
DESCRIPTION
● CCD SIGNAL PROCESSING:
Correlated Double Sampling (CDS)
Programmable Black Level Clamping
● PROGRAMMABLE GAIN AMPLIFIER (PGA):
–6dB to +42dB Gain Ranging
The VSP2262 is a complete mixed-signal processing
IC for digital cameras, providing signal conditioning
and Analog-to-Digital (A/D) conversion for the output
of a CCD array. The primary CCD channel provides
Correlated Double Sampling (CDS) to extract video
information from the pixels, –6dB to +42dB gain
range with digital control for varying illumination
conditions, and black level clamping for an accurate
black level reference. Input signal clamping and offset
correction of the input CDS are also performed. The
stable gain control is linear in dB. Additionally, the
black level is quickly recovered after gain change. The
VSP2262Y is available in an LQFP-48 package and
operates from a single +3V/+3.3V supply.
● 12-BIT DIGITAL DATA OUTPUT:
Up to 20MHz Conversion Rate
No Missing Codes
● 79dB SIGNAL-TO-NOISE RATIO
● PORTABLE OPERATION:
Low Voltage: 2.7V to 3.6V
Low Power: 83mW (typ) at 3.0V
Stand-By Mode: 6mW
