CXA1810AQ/AR
Luminance and Color Signal Processing for 8mm VCR
Description
The CXA1810AQ/AR is an IC designed for 8mm
VCR Y/C main signal processing for consumer use.
Equipped with many built-in filters, the
CXA1810AQ/AR is a one-chip main signal
processing system that greatly reduces the number
of external components.
