DESCRIPTION

The M52779SP is a single-chip semiconductor integrated circuit to process signals of a color TV. Circuits to process video IF, sound IF, video, color, and deﬂection signals, a I

2

C bus control circuit, and D/ A are build in this device. This IC can be used not only for popular-type TV sets but also for middle-class TV sets. Combined with a SECAM chroma decoder, the M52325AP, this de vice can process signals of every type of TVs in the world by discriminating them fully automatically.

FEATURES

•

A built-in I number of peripheral parts and rationalize production lines.

Various ﬁlters (TRAP, BPF, Y-DL, RGB clamp) are build in this IC.

•

PLL detection system is introduced to process video IF and voice

•

IF. Furthermore, AFT coil is not necessary. DL aperture control

•

Color signal frequency and vertical frequency of TVs of every

•

type can be discriminated fully automatically.

•

Horizontal/vertical countdown system

•

V-Ramp output

•

RGB output

•

Built in Y/C SW

ELECTRICAL CHARACTERISTICS TEST METHOD

P/N Video S/N

1. Input SG3 and measure the rms value of output signal at pin 52.

2. P/N is deﬁned as follows:

0NEG measured value (VP-P) ×10

P/N=20log

V

Measured value (mVrms)

BW Video frequency characteristics

1. Input SG4 and set the frequency f2 to 37.9MHz so that the beat element of 1MHz is output to pin 52.

2. Then set the applied voltage at pin 4 so that the beat element of 1MHz at pin 52 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.

IM Intermodulation

1. Adjust the applied voltage at pin 4 so that the lowest output signal voltage at pin 52 is 2.2V.

P52

2.2V

2. Measure elements of 1.07MHz and 4.43MHz of output at pin 52.

3. IM is deﬁned as follows:

IM=20log

Element of 1.07MHz

Element of 4.43MHz

LIM Input limiting sensitivity

Decrease the input level of SG 18. Measure the input level when the element of 400Hz at pin 46 is 3dB smaller than V

0AFM (S6:

Maximum AF output (6.0M)).

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 90dBu SG6.

2. VA is the output level at pin 52. Increase SG6 voltage until the output at pin 52 becomes 3dB smaller than VA. The input levell at that time is the maximum permissible input.
