M52775FP
VIF, SIF, VIDEO, CHROMA, DEFLECTION FOR NTSC DESCRIPTION
The M52775FP is desinged to provide a solution to NTSC color television system. It is an I C bus controlled NTSC 1 chip. It consists of various processing blocks such as video IF, sound IF, luminance, chrominance, mono-sound, OSD display, interface, H and V deflection. At each block, I2C control is possible and a total of 30 parameters can be controlled by I C bus.

INPUT SIGNAL PARAMETERS INCLUDING INPUT SIGNALS
1. Input signal name is two alphanumeric characters.
EX.) S S Standard Signal
Second character First character
First character:
Standard=S, Nonstandard=V (Modified parts should be specified.)
Second character: Meaning of signal 2. Structure of input color signal The following figure shows the structure of color signal.
ec(n) ec eb(n) eb H.sync 500mVP-P eb(n+1) ec(n+1)
13 14 15 16 17 20 22
1) When S (standard) is used as the first character, the standard color bar signal of each system is applied. H.sync should be added for input clamp. 2) Amplitude and frequency of burst are represented as ed. In case of standard signal, the amplitude is 285mVP-P. 3) Amplitude and frequency of chroma are represented as ec. In case of standard signal, the amplitude is 570mVP-P and the frequency is 3.579545MHz.
