MITSUBISHI ICs (TV)
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
2
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, I parameters can be controlled by I
2
C control is possible and a total of 30
2
C bus.

ELECTRICAL CHARACTERISTICS TEST METHOD
P/N Video S/N
1. Input SG3 and measure the rms value of output signal at pin 57.
2. P/N is defined as follows: V
P/N=20log
0NEG measured value (VP-P) ×10
Measured value (mVrms)
Vf Video frequency characteristics
1. Input SG4 and set the frequency f2 to 44.75MHz so that the beat
element of 1MHz is output to pin 57.
2. Then set the applied voltage at pin 60 so that the beat element of
1MHz at pin 57 may be 100dBµ.
3. Decrease f2 to the level at which the beat element becomes 3dB
smaller than the element of 1MHz, and read the value at that level.
P57
100dBµ
1MHz BW
Vin min. Input sensitivity
1. Decrease SG5 level until the video detector output is 3dB
smaller then the measured value of Parameter V3 “Video detector output”.
Vin max. Maximum permissible input
1. Input 90dBµ SG6.
2. V
A is the output level at pin 57. Increase SG6 voltage until the
output at pin 57 becomes 3dB smaller than VA. The input levell at that time is the maximum permissible input.
µAFTN AFT detector sensitivity V58H Maximum AFT voltage, V58L Minimum AFT voltage
