NTE1483 Integrated Circuit Video IF System Description: The NTE1483 is a silicon monolithic integrated circuit in a 22–Lead DIP type package designed for use in the PIF section in color TV receivers. As it contains a separate picture detector and sound IF detector, this device offers low buzz characteristics. The NTE1483 has all functions including picture IF amplifier (4th), picture low–level detector, sound IF detector, AFC detector, IF AGC, RF AGC and picture amplifier. Features: D Low Buzz Characteristics for Audio Multiplex TV D High Input Sensitivity D Wide AGC Control Range D Contains Differential Mode Input for use with SAW Filter Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Supply Voltage (Pin13), V13max . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15V Pin22 Current, I22max . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100mA Pin14 Current, I14max . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±3mA Power Dissipation (TA ≤ +65°C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 900mW Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –15° to +65°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –40° to +125°C Electrical Characteristics: (TA = +25°C, VCC = 12V, RA = 120Ω, fp = 58.75MHz unless otherwise specified) Parameter Symbol Test Conditions Min Typ Max Unit Total Supply Current ICC Zero Carrier 55 70 90 mA Pin13 Current I13 Zero Carrier 20 30 40 mA Pin22 Curent I22 Zero Carrier 35 40 50 mA Pin22 Voltage V22 6.6 7.2 7.6 V Maximum RF AGC Voltage V17H V16 = 7V 9.0 9.2 10.0 V Minimum RF AGC Voltage V17L V16 = 0 – 0 0.5 V Pin11 Voltage V11 3.7 4.1 4.7 V Electrical Characteristics (Cont’d): (TA = +25°C, VCC = 12V, RA = 120Ω, fp = 58.75MHz unless otherwise specified) Parameter Symbol Test Conditions Min Typ Max Unit 5.0 6.5 7.7 V Pin10 Voltage V10 Maximum AFT Output Voltage V10H V7 = 4.8V, V8 = 5.1V 11.0 – – V Minimum AFT Output Voltage V10L V7 = 5.1V, V8 = 4.8V – – 1.0 V Input Sensitivity vi(lim) fm = 400Hz, m = 40%, vo = 0.8VP–P 25 32 41 dBµ AGC Range G.R. fm = 10kHz, m = 40%, vo = 0.8VP–P 60 80 – dB Maximum Input Voltage vi(Max) fm = 10kHz, m = 40%, vo = 0.8VP–P 100 55 – mVrms Signal–to–Noise Ratio S/N fm = 15.75kHz, m = 80%, vo = 1.5VP–P, vi = 10mVrms 50 – – dB fm = 400Hz, m = 40%, vi(P) = 3mVrms, fs = 54.25MHz, vi(s) = 300µVrms 12 25 50 mVrms – 5 50 mVrms m = 40%, vi = 20mVrms 5 13 – MHz – 5 – % – 5 – deg SIF Output Voltage vo(SIF) Carrier Leak CL(DET) vi = 20mVrms Picture Frequency Response fC Differential Gain DG Differential Phase DP fp = 58.75MHz, Stair Step, fm = 3.58MHz, m = 85%, 14% Modulated White to Sync Level, vo(DET) = 1.4VP–P AFT Control Sensitivity Sf fm = 400Hz, m = 40%, vo = 0.8VP–P 50 150 – mV/kHz BW fm = 400Hz, m = 40%, vo = 0.8VP–P 0.2 1.1 2.1 MHz AFT Band Width PIF Input Resistance Ri – 1.5 – kΩ PIF Input Capacitance Ci – 3.5 – pF Pin Connection Diagram Video IF Output Video IF Output GND LLD Input SIF Output AFT Video Det Tuning Video Det Tuning AFT Tuning AFT Tuning Video Output 1 2 3 4 5 6 7 8 9 10 11 22 21 20 19 18 17 16 15 14 13 12 VCC 2 Compensation Compensation Video IF Input Video IF Input RF AGC Output RF AGC Control AGC Filter Keying Pulse VCC 1 AGC Level Control 22 12 .410 (11.41) 1 11 .400 (10.16) 1.300 (33.0) .216 (5.5) .100 (2.54) 1.000 (25.4) .110 (2.79)
