| NTE701 Integrated Circuit Video Signal Processor Description: The NTE701 is a monolithic integrated circuit TV signal processor in a 16-Lead DIP type package designed for use in color or monochrome receivers. Circuit functions include a horizontal oscillator with AFC, a sync separator, and a key AGC system. The AGC system provides output signals for IF (reverse) and tuner (forward and/or reverse). The wide frequency-range horizontal oscillator has high stability at 503.3kHz. Features: D Horizontal Oscillator with AFC D Sync Separator with Noise Immunity D Strobed AGC System D IF AGC Output D Delayed Outputs for Forward or Reverse AGC Tuners D Internal Noise Threshold D High-Impedance Video Input D RF AGC Delay Externally Controlled D Output Short-Circuit Protection Absolute Maximum Ratings: DC Supply Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15V Device Dissipation (Up to TA = +55C) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 750mW Derate Linearly Above +55C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7.9mW/C Operating Ambient Temperature Range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 to +85C Storage Temperature Range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -65 to +150C Lead Temperature (During Soldering, 1/16" from case, 10sec max) . . . . . . . . . . . . . . . . . . . . +265C Electrical Characteristics: (TA = +25C, Pin 5 to GND, Pin9 to12V unless otherwise specified) Parameter Power Supply Current Video Inverter Voltage Sync Separator Output Voltage, High Sync Separator Output Voltage, Low Video Noise Clamp Voltage AGC Discharge Current Symbol I9 V2 V3H V3L V3 I15 Test Conditions (Pins connected as Shown) Measure Pin9 Pin1 to 14V, Pin2: 12k to GND, Pin3: 27k to GND, Measure Pin2 Pin1 to 14V, Pin2: 12k to GND, Pin3: 27k to GND, Measure Pin2 Pin1 to 4V, Pin3: 27k to GND, Measure Pin3 Pin1 to 3.1V, Pin3: 27k to GND, Measure Pin3 Pin1 to 4.4V, Pin2: 10k to GND, Pin15: 470 to 6V, Pin16: 27k to 12V, Measure Pin15 Pin1 to 3.45V, Pin2: 10k to GND, Pin15: 470 to 6V, Pin16: 27k to 12V, Measure Pin15 Pin1 to 3.45V, Pin2: 10k to GND, Pin15: 4.7k to 6V, Measure Pin15 Adjust Pin1 for I15 = 00.1mA, Pin2: 10k to GND, Pin15: 4.7k to 6V, Pin16: 27k to 12V, Measure Pin1 Pin11: 10k to GND, Pin12: 40k to 12V, Pin13: 22k to 5V, Pin14: 1k to 2.95V, Pin16: 1k to 2.2V, Measure Pin15 Pin11: 10k to GND, Pin12: 10k to 12V, Pin13: 2.2k to 5V, Pin14: 1k to 2.95V, Pin15: 1k to 5.3V, Measure Pin11 Pin11: 10k to GND, Pin12: 10k to 12V, Pin13: 2.2k to 5V, Pin14: 1k to 2.95V, Pin15: 1k to 5.3V, Measure Pin12 Pin11: 10k to GND, Pin12: 10k to 12V, Pin13: 2.2k to 5V, Pin14: 1k to 2.95V, Pin15: 1k to 5.3V, Measure Pin13 Pin11: 3.6k to GND, Pin12: 3.16k to 12V, Pin13: 2.2k to 5V, Pin14: 1k to 2.95V, Pin15: 1k to 7.9V, Measure Pin11 Pin11: 3.6k to GND, Pin12: 3.16k to 12V, Pin13: 2.2k to 5V, Pin14: 1k to 2.95V, Pin15: 1k to 7.9V, Measure Pin12 Pin11: 10k to GND, Pin12: 10k to 12V, Pin13: 2.2k to 5V, Pin14: 1k to 2.95V, Pin15: 1k to 7.9V, Measure Pin13 Pin2: 10k to GND, Pin2 to GND, Pin4: 5k to 3.8V, Pin10: 10k to 6V, Limit GND at Pin3 to 10sec, Measure Pin10 Connect OSC-loop to Pin6, Pin7, & Pin8, Pin3 to GND for 10sec max, Measure Pin6 Connect OSC-loop to Pin6, Pin7, & Pin8, Pin3 to GND for 10sec max, Measure Pin6 10.7 0.6 Min 10 5.2 10.7 Typ - - - - - - Max 22 6.4 - 1.3 - 1.4 Unit mA V V V V mA AGC Charge Current I15 -2.1 - -4.8 mA A V AGC Comparator Leakage Current AGC Threshold Voltage I15 V1TH -20 3.8 - 4.0 +20 4.3 Minimum IF AGC V13L 0.75 - 1.25 V A A Forward Tuner AGC Leakage Current Reverse Tuner Leakage Current I11 -20 - +20 I12 -10 - +10 IF AGC High Voltage V13H 3.65 - 4.15 V Forward Tuner AGC Voltage, Low Reverse Tuner AGC Voltage, Low Maximum IF AGC Voltage V11L 0.8 - 3.2 V V12L 1.65 - 3.25 V V13H 4.85 - 5.20 V A Phase Detector Leakage Current Phase Detector Bias Voltage Oscillator Output Voltage Oscillator Free-Running Frequency I10L -5 - +5 V4 V6 f6FR 2.65 0.6 475 - - - 3.10 1.6 535 V VP-P kHz Electrical Characteristics (Cont'd): (TA = +25C, Pin 5 to GND, Pin9 to12V unless otherwise specified) Parameter Oscillator Frequency, High Symbol f6H Test Conditions (Pins connected as Shown) Connect OSC-CKT to Pin10, Pin7, & Pin8, Pin2: 10k to GND, Pin4: 5k to 18V, Measure Pin6 Connect OSC-CKT to Pin10, Pin7, & Pin8, Pin2: 10k to GND, Pin4: 5k to 3.8V, Measure Pin6 Pin3: 10 to GND 10sec max Pin8: 10 to GND for 10sec max, Pin3: 10 to GND for 10sec max Pin Connection Diagram Video Input Sync Sep Comp Sync Input Horiz Sawtooth Input GND OSC Phase Input OSC Quad Input OSC Output 1 2 3 4 5 6 7 8 16 Horiz Pulse Input 15 AGC Filter 14 IF Gain Clamp 13 IF AGC 12 Tuner Rev AGC 11 Tuner Fwd AGC 10 Horiz AFC Filter 9 VCC Min 520 Typ - Max - Unit kHz Oscillator Frequency, Low f6L - - 485 kHz Sync Separator Short Circuit Oscillator Output Short Circuit I3Max I8Max - - - - 40 130 mA mA 16 9 1 8 .260 (6.6) Max .200 (5.08) Max .870 (22.0) Max .100 (2.54) .700 (17.78) .099 (2.5) Min |
