NTE1538 Integrated Circuit TV Horizontal/Vertical OSC Driver Description: The NTE1538 is a multifunctional integrated circuit in a 16–Lead DIP type package containing various functions required for synchronization, deflection of color television sets. This device has been developed under the design concept that the basic characteristics should be made more complete and the television sets incorporating the NTE1538 should be streamlined by making the device compact and by minimizing the number of parts required. Functions: D Synchronizing Separation D Horizontal Oscillation D Vertical Drive D Vertical Blanking D Horizontal AFC D Vertical Oscillation D X–Ray Protection Features: D Multifunctional and Compact D Minimum Number of Parts Required D Horizontal, Vertical Oscillators are Stable Against Variations in Ambient Temperature and Supply Voltage due to Small Warm–Up Drift. D Small Variation in Horizontal Oscillation Frequency D Good Linearity and Interlace because DC Bias at Vertical Output Stage is Subjected to Sampling Control within Retrace Time. D Vertical Blanking Pulse Width can be Set Freely According to Peripheral Parts Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Maximum Supply Voltage, V12 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14V Maximum Supply Current, I15 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16mA Allowable Power Dissipation (TA = +60°C), PDmax . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 450mW Operating Temperature Range, Topg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –20° to +85°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –55 to +125°C Recommended Operating Condition: (TA = +25°C unless otherwise specified) Recommended Supply voltage, V12 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12V Electrical Characteristics: (TA = +25°C, V12 = 12V, ICC15 = 13mA unless otherwiss specified) Parameter Symbol Test Conditions Min Typ Max Unit VCC12 Current Dissipation ICC12 13.0 – 20.0 mA VCC15 Supply Voltage VCC15 11.8 – 13.2 V 9.0 – 11.0 Hz 50 – 60 Hz –0.5 – 0.5 Hz –0.028 – 12 – 17 dB fH center 15.734kHz –750 – 750 Hz Supply Voltage Dependence Horizontal Frequency VZ – VZ X 90% –50 – 50 Hz Temperature Characteristic of Horizontal Frequency TA = –10° to +60°C –3.4 – 3.4 Hz/°C Horizontal Output Pulse Width fH = 15.734kHz 21.5 – 26.5 µs 3.8 – 7.2 mA Vertical Frequency Pull–In Range Vertical Free–Running Frequency fV fV center 55Hz Supply Voltage Dependence of Vertical Frequency V12 = 12 ±1V, 55Hz at 12V Temperature Characteristic of Vertical Frequency TA = –10° to +60°C Vertical Driver Amplification Factor Horizontal Free–Running Frequency fH Horizontal Output Drive Current Pin Connection Diagram AFC Output 1 16 AFC Input 15 VCC (115V) 14 Sync Separator Input Separator 13 Sync Output 12 VCC Horiz OSC Input 2 Horiz OSC Output 3 X–Ray Protect 4 GND 5 Vert Output 6 11 Vert OSC Input Vert Driver Input 7 10 Vert OSC Input Vert Driver Input 8 9 16 Vert Blank Output 9 .260 (6.6) Max 1 8 .785 (19.9) Max .300 (7.62) .200 (5.08) Max .245 (6.22) Min .100 (2.54) .700 (17.7) –0.028 Hz/°C
