M52303ASP

The M52303ASP is a type of single-chip semiconductor combined circuit that processes color NTSC system television signals. It features a variety of signal processing functions consisting of video IF, second IF, picture, color, and defiec tion signal processing. It also connects tuner and simple transistor output level to faculitate practical PAL/NTSC syst em color television set design.

Features of M52303ASP are: (1)with the exception of tuner and otput level, all color television signal processing func tions are built in. enhancing practically and reliability of the television set itself while contributing to lower power con sumption; (2)the intermediate frequency input pins include two pins for actuation input and feature high stability tow ard oscillation; (3)enables use of AFT defeat, picture muting, and sound muting; (4)features direct current control for picture quality, contrast, luminance, color saturation, and volume; (5)equipped with built in on screen character displ ay circuit.

The absolute maximum ratings and electrical characteristics of the M52303ASP can be summarized as: (1)supply volt age: 10.8V; (2)power dissipation: 1.4W; (3)operating temperature: -20 to 65 ;(4)storage temperature:-40 to 125. Electrical characteristics:(1)circuit current: 27mA min, 3G mA typ and 50mA max; (3)video output DC voltage: 4.55V min, 4.0V typ and 5.53V max; (3)video output signal voltage: 1.7Vp-p min, 2.0Vp-p typ and 2.3Vp-p max, etc.
