7 / 108 page TA1360ANG 2005-08-18 7 Pin No. Pin Name Function Interface Circuit Input Signal/Output Signal 22 H-FREQ SW2 Switches horizontal frequency (Switch 2). Leave this pin open when horizontal frequency is switched by Bus controlling. Controlling this pin prevails over Bus control. (Refer to Table 1: Bus control function.) When this IC is used for CRT, frequency of horizontal output (pin 26) is controlled according to voltage of this pin. DC voltage that is generated by dividing resistor of DEF VCC (pin 19) should be used to control this pin. At BUS control (horizontal frequency) : output voltage value 28 k/15 kHz : DC 9 V 31 kHz : DC 6 V 33 kHz : DC 3 V 37 k/45 kHz : DC 0 V At pin 22 control, horizontal frequency and input voltage value 0 to 1.0 V : 37 k/45 kHz 2.0 V to 4.0 V : 33 kHz 5.0 V to 7.0 V : 31 kHz 8.0 V to 9.0 V : 28 k/15 kHz 23 H CURVE CORRECTION Adjusts screen curve at high voltage fluctuation. Input AC component of high voltage fluctuation. When not used, connect 0.01-µF capacitor between this pin and GND. DC 24 FBP IN Inputs FBP for horizontal AFC. Sets H-BLK width. 25 DEF/DAC GND GND pin for DEF/DAC block ⎯ ⎯ 26 H-OUT Horizontal output pin. Open-collector output. 27 VP OUT Outputs vertical pulse. Applying current to this pin, performs external blanking by OR-ing with internal blanking. Note: Changing H-position varies VP output width. Use the start phase only for VP output. VP output: V-BLK input current: 780 µA to 1 mA 23 1 kΩ 19 25 6.5 V 24 19 25 500 Ω 20 kΩ 19 26 25 5 kΩ 19 25 27 200 Ω 32 5 V 0 V Start phase 19 25 22 1 kΩ 30 kΩ 4.5 V 7.5 V 1.5 V max: 9 V H-AFC threshold : 5.3 V BLK threshold : 2.3 V |
