CXA2019AQ Datasheet, PDF (1/30 Pages) Sony Corporation – NTSC/PAL Chroma Decoder

NTSC/PAL Chroma Decoder
CXA2019AQ
Description
The CXA2019AQ is a bipolar IC which integrates
the luminance signal processing, chroma signal
processing, and sync signal processing functions for
NTSC/PAL system color TVs onto a single chip.
40 pin QFP (Plastic)
Features
• Sub picture bright and white balance can be
adjusted by using the main picture Y/C/J BGP
output as the timing pulse
• I²C BUS compatible; two bus lines (SCL, SDA)
allow various adjustments and user controls
• Countdown system eliminates need for H and V
oscillator frequency adjustment
• Non-adjusting Y system filters (chroma trap, delay
line)
• Automatic identification of color system (forced
control possible)
• Automatic identification of 50/60Hz vertical frequency
(forced control possible)
• Built-in delay line aperture correction
• Built-in dynamic picture (black expansion) function
• Combination with a non-adjusting SECAM chroma
decoder allows configuration of multiple systems
