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. Features Carrier balance adjustment unnecessary (Carrier leak above 36 dB against burst) High S/N Low power consumption (140mW) Applications CCD camera Absolute Maximum Ratings (Ta = 25°C) Supply voltage VCC 7 V Storage temperature Tstg –65 to +150 °C Allowable power dissipation PD 600 mW Block Diagram and Pin Configuration
