BL8531H
AFE FOR CCD/CIS SIGNAL PROCESSOR
GENERAL DESCRIPTION
The samsung analog front end(AFE) for CCD/CIS image signal is an integrated analog signal processor for color
image signal.
The AFE converts CCD/CIS output signal to digital data. The AFE includes three-channel CDS(Correlated
Double Sampling) circuit, PGA(Programmable Gain Amplifier), and 12-bit analog to digital converter with
reference generator.
A parallel data bus provides a simple interface to 8-bit microcontroller.
APPLICATIONS
• Color and B/W Scanner
• Digital Copiers
• Facsimile
• General Purpose CCD/CIS imager
FETURES
• 12-bit 6MSPS A/D Converter
• Integrated Triple Correlated Double Sampler
• 3-Channel 2 MSPS Color Mode
• Analog Programmble Gain Amplifier
• Internal Voltage Reference
• Wide clamp level controllability for CIS sensor
• No Missing Code Guaranteed
• Microcontroller-Compatible Control Interface
• Operation by Single 5V Supply
• CMOS Low Power Dissipation
KEY SPECIFICATION
• Resolution: 12-bit
• Conversion Rate: 6 MHz(2 MHz*3)
• Supply Voltage: 5 V ± 5%
• Power Dissipation: 375 mW(Typical)
