CIP3250:
The IC is used to interface the analog input, which is output from the PIP module (SCART RGB or PIP RGB). As can be seen
from the block diagram, there is a CT-BR-SAT block, which is used for luma contrast, brightness, hue, and color saturation
correction. The soft mixer is controlled by the fast blank signal.
Features:
n
analog input for RGB or YUV and Fast Blank
n
triple 8 bit analog to digital converters for RGB/YUV with internal programmable clamping
n
single 6 bit analog to digital converter for Fast Blank signal
n
digital matrix RGB % YUV (Y, BY, RY)
n
luma contrast and brightness correction for signals from analog input
n
color saturation and hue correction for signals from analog input
n
digital input for DIGIT 2000 or DIGIT 3000 formats
n
digital interpolation to 4:4:4 format
n
high quality soft mixer controlled by Fast Blank signal
n
programmable delays to match digital YUVin and ana-log RGB/YUV
n
variable low pass filters for YUV output
n
digital output in DIGIT 2000 and DIGIT 3000 formats, as well as RGB 4:4:4
n
I2C bus interface
n
clock frequency 13.5... 20.25 MHz
