| NTE1664 Integrated Circuit TV Hotizontal/Vertical Sync Signal Processor Description: The NTE1664 is a silicon monolithic integrated circuit in a 22-Lead DIP type package designed for use as a horizontal deflection circuit and vertical deflection circuit for color TV sets. This device contains two synchronization signal separators, a vertical oscillator, vertical sawtooth shaper, vertical pre-driver, vertical retrace blanking pulse generator, horizontal AFC, horizontal oscillator, horizontal pre-driver, and an abnormal high voltage prevention circuit. Features: D Two Synchronous Signal Separators for Very Stable Synchronization (Horizontal and Vertical Signals are Independent of Each Other) D Remarkably Improved Interlace Tracking due to Separate Wiring of Horizontal and Vertical Sections D Wide Range of Vertical Retrace Blanking Time due to Adjust Pin D Very Low Oscillation Frequency Drift of Vertical and Horizontal Oscillator Against Ambient Temperature Absolute Maximum Ratings: (TA = +25C 3C unless otherwise specified) Vertical Power Supply Voltage, V21 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15V Horizontal Power Supply Current Drain, I11 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30mA Vertical Output Current, I14 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -30mA to +0mA Horizontal Output Current, I10 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -10mA to +10mA Power Dissipation (TA = +75C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 600mW Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -20 to +75C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 to +125C Recommended Operating Conditions: (TA = +25C unless otherwise specified) Vertical Power Supply Voltage, V21 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12V Horizontal Power Supply Drain Current, I11 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15mA Electrical Characteristics: (TA = +25C, V21 = 12V, I11 = 15mA unless otherwise specified) Parameter Vertical Power Supply Current Horizontal Power Supply Voltage Vertical Free-Running Frequency Vertical Free-Running Frequency Drift Symbol I21 V11 fo fo(VCC) fo(TA) Vertical Synchronizing Capture Frequency Output Middle Voltage Output Middle Voltage Drift Retrace Pulse Width fp Test Conditions V21 = 12V I11 = 15mA C18 = 1F, R17 = 33k Min 10.5 12.0 48 0 0 46 Typ 14.0 13.0 50 0.8 0.6 48 13 - 1.0 2.0 11 - 700 40 300 15.75 - 40 26.0 11 -4.5 - Max 17.5 14.5 53 1.0 1.0 50 14 1.0 1.05 2.1 - 130 900 45 420 16.50 50 100 27.5 - -6.0 +0.1 Unit mA V Hz Hz Hz Hz V V ms ms VP-P mV Hz Hz/A A/rad kHz Hz Hz VP-P mA V fo(VCC) = |fo(9.6V) - fo(14.4V)| fo(TA) = |fo(-20C) - fo(+75C)| Output Power: NTE1676 VMID 12 0 0.95 1.9 10 VMID(TA) VMID(TA) = |VMID(-20C) - VMID(+75C)| RPW (1) RPW (2) C13 = 0.047F, R13 = 30.75k C13 = 0.1F, R13 = 28.5k V11(TA) = |V11(-20C) - V11(+75C)| C5 = 5600pF Retrace Pulse Voltage Horizontal Power Supply Voltage Drift Horizontal Synchronizing Capture Frequency Efficiency of Horizontal Oscillation Control AFC Detector Gain Horizontal Free-Running Frequency Horizontal Free-Running Frequency Drift RPV V11(TA) fPH fHO fHO(I11) fHO(TA) C5 = 5600pF, R5 = 14.5k fHO(I11) = |fHO(15mA) - fHO(9mA)| fHO(TA) = |fHO(-20C) - fHO(+75C)| - 500 38 190 15.00 0 0 24.5 10 -3.5 Horizontal Output Pulse Width Horizontal Output Pulse Voltage Horizontal Output Current X-Ray Protector Input Voltage PWH PWV I10 V6 V7 = 6.2V -0.1 Pin Connection Diagram Horizontal Sync Signal Separator Input Horizontal Sync Signal Separator Output AFC Detector Input AFC Detector Output Horizontal OSC Input X-Ray Protect Input X-Ray Protect Reference X-Ray Protect Input GND (Horizontal) 1 2 3 4 5 6 7 8 9 22 Vertical Sync Signal Separator Input 21 VCC (Vertical) 20 Vertical Sync Signal Separator Output 19 Vertical Sync Signal Input 18 Vertical OSC (Charge) 17 Vertical OSC (Discharge) 16 GND (Vertical) 15 Vertical Feedback 14 Vertical Amp Output 13 Vertical Blank Pulse Width Adjust 12 Vertical Blank Pulse Output Horizontal Pulse Output 10 VCC (Horizontal) 11 22 12 .410 (11.41) 1 11 1.300 (33.0) .216 (5.5) .400 (10.16) .100 (2.54) 1.000 (25.4) .110 (2.79) |
