CXD3422GA
Timing Generator and Signal Processor for Frame Readout CCD Image Sensor
Description
The CXD3422GA is a timing generator and CCD
signal processor IC for the ICX284, ICX432/434
CCD image sensor.
96 pin LFLGA (Plastic)
Features
• Timing generator functions
• Horizontal drive frequency 18 to 24.3MHz
(Base oscillation frequency 36 to 48.6MHz)
• Supports frame readout/draft (sextuple speed)/
AF (Auto focus drive) (ICX432 mode)
• Supports frame readout/draft (quadruple speed)/
AF (Auto focus drive) (ICX434 mode)
• High-speed/low-speed shutter function
• Horizontal and vertical drivers for CCD image
sensor
• CCD signal processor functions
• Correlated double sampling
• Programmable gain amplifier (PGA) allows gain
adjustment over a wide range (–6 to +42dB)
• 10-bit A/D converter
• Chip Scale Package (CSP):
CSP allows vast reduction in the CCD camera
block footprint
Applications
Digital still cameras
