Synchronous Mode The composite signal or synchronous signal input to pin-11 (SYNCIN). The signal that was input to pin-11 (SYNCIN) is separated synchronous. The pin-9 (HSYIN) input external synchronous signal without fail. In the case that HSY (Horizontal synchronous pulse) is not input, NJM2527 does not do a normal action, because inside clamp pulse does not generate. 2. Color Signal Play Mode 1) ACC Circuit (Automatic Chroma Control) The chroma signal input to pin-13 (CIN), and detect the burst-signal through the HPF circuit, and controlled stable burst-signal feedback from demodulate output. When the pin-13 is GND level, the mode is composite input, and pin-28 (VIDEOIN) composite-video signal input to ACC circuit. 2) APC Circuit, and VCXO (Automatic Phase Control) The burst signal level of chroma is constant by ACC circuit. The PLL circuit consists of VCXO and locked burst signal. The pin-19 (TINT) input DC voltage adjust the VCXO phase, and adjust the demodulate axis. When the pin-19 is GND, the mode is PAL, and only accepts analog RGB input. 3) Color Killer The chroma signal is output to demodulator when PLL locked, and the color killer is - 42dB(NTSC). 4) IDENT Circuit NJM2527 synchronizes to H-SYNC in PAL mode. And, the career is reversing 90-degree phases. IDENT circuit arranges the flip-flop polarity (that is driven by HD) and the color burst phase of the chroma signal that are input from 13-Pin (CIN). In the case that IDENT circuit does not act normally, Color-Killer acts, and the chroma signal is not output to de-modulator. 5) CLEANING Cleaning filter avoids receiving the influence of burst signal noise that is input to APC and ACC circuit by tuning circuit. Chroma phase can be adjusted by utilizing this cleaning filter. 6) Color Circuit This circuit adjusts the color TINT. The pin-20 (COLOR) adjusts the chroma signal range from ACC circuit. This signal demodulator without burst signal by burst gate pulse (BGP). 7) DEMOD This DEMOD circuits demodulate color differential signal after the ACC circuit. The RGB signal consists of color differential and Y signal by matrix circuit, and input to Int./Ext. signal switches. 3. Y-signal Mode 1) TRAP The composite video signal input to pin-28 (VIDEOIN) without the chroma by TRAP circuit. The TPAP frequency is 3.58MHz or 4.43MHz, and not through when Y/C input mode. 2) Picture Circuit The Y/composite-signal input to pin-28 (VIDEOIN) without the synchronous signal. The pin-27 (PICTURE) adjusts the frequency characteristic around 2MHz and emphasizes the outline. The pin-27 level emphasizes outline depend on the DC voltage. includes second differential circuit. 4. INT./EXT. Signal Switch Mode The analog RGB signal (0.7VP-P typ.) input to pin-37, pin-35, and pin-33, and these signal clamps pedestal. The ext-signal select Y/C-signal or Int-signal by pin-7 (SW). Ver.3 - 32 - NJM2527 5. RGB Signal Mode 1) Contrast The pin-31 (CONTRAST) adjusts the all of RGB signal, which is black-to-white range. 2) Gamma Amplifier This circuit is non-liner amplifier to adjust the RGB signal equal to the luminous gamma characteristics. There is two-point adjustment for accurate correction. The pin-38 (VG1) adjusts low side, and the pin-39 (VG2) adjusts high side. Input Signal VG1 adjust VG2 adjust 3) Sub Gamma Circuit This circuit adjusts gamma characteristics of B/R signal, and sub gamma adjusts white-balance for the monitor. The pin-40 (SUBVG1R) and pin-42 (SUBVG2R) adjust low side with R-signal and high side with gamma characteristics. The pin-41 (SUBVG1B) and pin-43 (SUBVG2B) adjust low side with B-signal and high side for gamma characteristics. These terminal controls R-signal and B-signal separately. 4) Bright The pin-45 (BRIGHT) clamps the pedestal after the brightness adjustment (black to black). 5) Side Black The side-black circuit output black level, when the mode is black mask for wide picture. The RGB signal is black level when pin-44 (SIDEBLACK) input signal is low period only. 6) Output Amplifier The pin-5 (FRP) input to the timing pulse with inverting RGB output, and output the inverting RGB signal per every 1H. The RGB outputs are: FRP-High: Non-inverting output FRP-Low: Inverting output The center voltage is preset to half of Vcc2.
