    CIRCUIT DESCRIPTION...
  • Page 99 CIRCUIT DESCRIPTION (Note) In regard to the contents of the text, please refer also to the relevant circuit dia- grams. µ Power unit block [Including the power-related -COM (microcomputer) operation] • When a commercial power input is fed from an AC inlet, the power unit begins to generate an output of M+7V for the µ-COM system.
  • Page 100 VIDEO PWB Block 1. AUDIO block The AUDIO signal input entered from M1008 to M1010 is controlled and selected by I2C bus control of IC5001 (MM1311BD: SW). The selected AUDIO signal is output from the AB connector to the AUDIO AMP module via IC5002 (BA4558: buffer).
  • Page 101 4. VIDEO block The external VIDEO signal input is entered from M1001 to M1003, and selected at IC5001 (MM1311BD: SW). The composite signals of the IC5001 output are applied to the ternary Y/C separator circuit and the 3-line Y/C separator circuit. The Y/C signal input separated at each Y/C separator circuit is entered in IC5306 to 5309. At the same time, the composite signals are also entered in IC5306 to 5309 directly.
  • Page 102 C-VIDEO Signal Y FL5301 IC5313 FL5304 Q5320 Ternary Y/C 6MHz LPF 6MHz LPF ~5322 ; AMP separator circuit Q5302 ‘ Q5305 ; FL5305 Q5324 IC5312 6MHz LPF ~5326 ; AMP Memory Signal C (2) 3-line Y/C separation The VIDEO signal output of Q5018 is processed for band limitation at FL5301. It is then processed for the level and Characteristic F compensation at the AMP (Q5302 to Q5305) in the latter stage.
  • Page 103 (3) PAL/NTSC decoding After passing through the built-in delay line of IC5504, the Y signal is then output from Pin 4. This signal is applied to Pin 15 of IC5503 (CTI) and double-amplified there. The resultant output is then generated from Pin 2.
  • Page 104 (4) SECAM decoding When a color signal of SECAM is received, IC5510 (SECAM decoding) receives the control signal from Pin 3 of IC5504 (PAL/NTSC). Inside the IC5510 (SECAM decoding), the chroma signal input of Pin 24 is processed for band limitation at the bell filter and is then amplified at the limiter circuit.
  • Page 105 MAIN PWB Block 1. Video signal processor block In the MAIN PWB, each video signal selected at the VIDEO PWB is converted into a digital signal for the purpose of various signal processing such as enlargement, contraction, and so on. The processed signal output is sent to the plasma display module.
  • Page 106 (3) Flow of 480P, 720P (chrominance input), and 480P, 720P (RGB input) signals Converter 422→RGB "YU" 30MHz IC6501 IC7501 γ Process Parallel→ Change Size Select Enhance/NR On screen serial IC8502 IC9000 IC8003 IC9000 IC9403, 4 The chrominance (or RGB) signal input entered from the YU connector is converted into a digital signal at the AD converter, IC6501.
  • Page 107 When the RGB3 input is entered, the digital RGB signal input from the PL1 connector is of the serial data and it is converted into the parallel data at the panel link receiver, IC7002. (Processing of RGB x 8 bits x 2 phases = 48 lines) IC7501 sends out an output signal of IC7002 to IC8502.
  • Page 108 (8) AD converter (IC6501, IC6701) block IC6501 and IC6701 are the ICs intended for the conversion of analog RGB signals into 8-bit digital signals. (However, there are 48 output lines in total, each RGB color 8 bits x 2.) In addition to the functions of AD converter, this type of IC is also provided with the various functions of analog amplifier and PLL/VCO.
  • Page 109 (12) Definition conversion processing block (IC8502) Using the SDRAM (consisting of IC8503 and IC8504), IC8502 performs the conversion of the XGA signal to a level equivalent to VGA, the modification of the screen size for normal, full, etc., zoom operation, and the movement of the screen position.
  • Page 110 (3) Gate array block (Pre G/A IC7501) IC7501 is used as a timing controller intended to generate a variety of timing pulses based on the clock and horizontal sync signals from IC6701 (AD converter) and the vertical sync signal input entered from the YU connector and the PC connector (Pin 12).
  • Page 111 (2) Auto-picture function In IC7501, the screen position data are computed according to the input video signal when the auto-picture feature is turned ON for the RGB input. During the entry of RGB3 input, the screen position data are computed based on the DE signal sent from IC7002. The microcomputer picks up the screen position data from IC7501, and sets up the screen position in IC7501 and IC8502 based on the obtained data.
  • Page 112 (7) Control lock block When S2001 is turned on (pressed condition) inside the 232C PWB, Pin 19 of the microcomputer IC9501 is turned “H” and all keys other than the POWER key of the set main body are disabled. (8) PDP module control block With the PDP module, information about the screen position and input signals is controlled by the micro- computer through the bus SDATA, SCK, and LE.
