9 / 66 page TB1261F/TB1262F 2002-6-30 9 / 66 Pin # Description 35 (31) DIG. VDD ; DIG. VDD ; DIG. VDD ; DIG. VDD ; A Vdd terminal for of digital block. Supply HVcc voltage through 270 ohms of resistance. The coupling capacitor should be 10uF or less, in order to keep rise up time good enough. The voltage of this terminal is clipped to approximately 3.3V by the internal regulator. 36 QFP only Da Da Da Dac2; c2; c2; c2; A terminal to be output High/ Low status by an open collector interface. The pull up resistance should be fixed as a sink current is 1mA or less and the voltage is less than the voltage of H Vcc. 37 (32) FBP IN; FBP IN; FBP IN; FBP IN; An input terminal for FBP. V/GP pulses are output over this FBP. The Threshold levels are; 1.4 V ; for Blanking 3.7 V; for HAFC2 38 nc; 39 (33) H OUT; H OUT; H OUT; H OUT; An output terminal for horizontal driving pulses.; 40 QFP only VD OUT; VD OUT; VD OUT; VD OUT; An output terminal for VD pulses. The pulses are 3V for its level. 41 QFP only HD OUT; HD OUT; HD OUT; HD OUT; An output terminal fot HD pulses. GP Pulses are overlaid as SCP. Also BPP is overlaid to stop black stretch detecting. Those levels are 5V; for GP out 3V; for HD out 0.7V; for BPP in 42 QFP only Sync out; Sync out; Sync out; Sync out; An output terminal of the sliced sync pulses. Pull up this pin with 5.1kΩ of resistance. 43 (34) H AFC H AFC H AFC H AFC F F F Filter ilter ilter ilter;;;; A terminal should be connected with H. AFC Filter. The DC voltage of this pin controls the H VCO frequency. 44 QFP only Y3/CVBS3 IN; Y3/CVBS3 IN; Y3/CVBS3 IN; Y3/CVBS3 IN; An alternative input terminal for; - Y + Sync signals of Y/Cb/Cr_3 - Or CVBS_3 Those two are selected by IICBUS This terminal is clamped by charging / discharging the coupling capacitors. It is recommended that input impedance is kept at or below 100Ω. Input level 1Vp-p/140IRE 45 (35) H VCC (9V); H VCC (9V); H VCC (9V); H VCC (9V); A Vcc terminal for DEF circuit, HOUT, IICBUS POR, etc. Supply 9V.; Pin # Description 46 (36) V RAMP; V RAMP; V RAMP; V RAMP; A terminal should be connected with a capacitor to generate the V.Ramp signal.Connect this pin to GND via 0.47uF.The V.Ramp amplitude is kept constant by the V.AGC.; 47 (37) V OUT; V OUT; V OUT; V OUT; An output terminal for the vertical saw tooth wave. 48 49 QFP only Cb3 IN; Cb3 IN; Cb3 IN; Cb3 IN; Cr3 IN; Cr3 IN; Cr3 IN; Cr3 IN; Input terminals for ; - Cb and Cr signals of Y/Cb/Cr_3 These terminals are clamped by charging / discharging the coupling capacitors. It is recommended that input impedance is kept at or below 100Ω. 50 (38) DIG GND; DIG GND; DIG GND; DIG GND; A GND terminal for digital block.; 51 52 (39) (40) Cr OUT; Cr OUT; Cr OUT; Cr OUT; Cb OUT; Cb OUT; Cb OUT; Cb OUT; Output terminals for demodulated Cb and Cr signals. 53 (41) Y/Mon OUT Y/Mon OUT Y/Mon OUT Y/Mon OUT An alternative output terminal for; - Y signal after Y1 process - Or Mon out after selector Those two are selected by IICBUS 54 (42) BLACK DET; BLACK DET; BLACK DET; BLACK DET; A terminal should be connected with Black level detecting filter for black stretch. This terminal voltage controls the Black stretching gain. The IIC Bus controls the on/off and start point of the Black stretch. ; 55 (43) Y2/CVBS2/G IN Y2/CVBS2/G IN Y2/CVBS2/G IN Y2/CVBS2/G IN An alternative input terminal for; - Y + Sync signals of Y/Cb/Cr_2 in - Or CVBS_2 - Or G signal of Scart Y/R/G/B in Those three are selected by IICBUS. These terminals are clamped by charging / discharging the coupling capacitors. It is recommended that input impedance is kept at or below 100Ω. 56 57 (44) (45) Cb2/B IN; Cb2/B IN; Cb2/B IN; Cb2/B IN; Cr2/R IN; Cr2/R IN; Cr2/R IN; Cr2/R IN; Alternative input terminals for; - Cb and Cr signals of Y/Cb/Cr_2 - Or R and B signal of Scart Y/R/G/B in Those three are selected by IICBUS These terminals are clamped by charging / discharging the coupling capacitors. It is recommended that input impedance is kept at or below 100Ω. 58 (46) C C C C----IN; IN; IN; IN; An input terminal for chroma signal (standard burst amplitude level 286mVp-p). The dc level of this pin can be read by bus to detect if S port is connected or not.; |
