BA7230LS - NTSC color TV signal encoder

Multimedia ICs NTSC color TV signal encoder BA7230LS The BA7230LS comprises an RGB signal matrix circuit, balanced modulator circuit (rectangular 2-phase modulation), oscillator circuit (VCXO) for a 3.58MHz subcarrier synchronized with video input burst signals, luminosity and color difference signal mixing circuit, and a high speed switch for selecting composite signals of video input and RGB input.

RGB signals, synch signals, BFP (burst flag pulses), PCP (pedestal clamp pulses) are input, and

BA7230LS Features

* 1) Allows superimposition of video images (VIDEO IN) and computer images (RGB IN). 2) During superimposition, the subcarrier locked onto the video input burst signal RGB is modulated with the RGB signals by the APC circuit, preventing unnatural color disturbance due to switching. 3) Both t
