CXA1592Q

CXA1592Q/R Encoder for CCD Color Camera Description The CXA1592Q/R is a bipolar IC developed as an encoder for CCD color cameras. Color difference and luminance signals are input to be output as composite video and Y/C separate signals. The CXA1592 is a variant of the CXA1392 in which the down/up ratio and level of shapness signal have been changed from 1 : 3 to 1.5 : 1.5.
