NTE700 Integrated Circuit TV Chroma System Description: The NTE700 is a monolithic integrated circuit in a 16–Lead DIP type package that performs the functions of subcarrier regeneration, ACC and APC detection, and tint control in color television receivers. It is designed to function compatibly with the NTE743 TV Chroma Amplifier/Demodulator in a 2–package chroma system. The NTE700 is a TV Chroma System equivalent to the NTE982 except that the typical supply voltage is +12V and no internal shunt regulator is incorporated. Features: D Voltage–Controlled Oscillator D Keyed APC and ACC Detectors D DC Hue Control D Operates From +12V Absolute Maximum Ratings: DC Supply Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15V Device Dissipation (Up to TA = +55°C) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 630mW Derate Linearly Above +55°C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6.6mW/°C Operating Ambient Temperature Range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –40° to +85°C Storage Temperature Range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –65° to +150°C Lead Temperature (During Soldering, 1/16” from case, 10sec max) . . . . . . . . . . . . . . . . . . . . +265°C Electrical Characteristics: (TA = +25°C, V+ = 12V unless otherwise specified) Parameter Symbol Test Conditions Min Typ Max Unit Static Characteristics Supply Current I+ 12 – 24 mA Oscillator Current I2 4.25 – 8.55 mA ACC Output Balance Measure Pin15 to Pin16 –330 – 300 mV APC Output Balance Measure Pin11 to Pin12 –450 – 450 mV Oscillator Balance Measure Pin7 to Pin8 –330 – 330 mV Electrical Characteristics (Cont’d): (TA = +25°C, V+ = 12V unless otherwise specified) Parameter Symbol Test Conditions Min Typ Max Unit – – – Hz –400 – 400 Hz – – 175 Hz Dynamic Characteristics (eIN = 0.4VP–P Sine Wave) Oscillator Center Frequency fO Oscillator Frequency Deviation fO1 Oscillator Frequency Deviation |∆fO| Set R for fO = 3.579545 ±5Hz V+ = 12V ±1V Oscillator Pull–In Range, High Side Osc. must pull–in and lock to eIN at: fIN = 3.579745MHz 200 – – Hz Oscillator Pull–In Range, Low Side Osc. must pull–in and lock to eIN at: fIN = 3.579345MHz –200 – – Hz Dynamic ACC Measure Pin15 to Pin16, Record value (V1) –75 – 75 mV ACC Control Measure Pin15 to Pin16, fIN = 3.579545MHz Record Value (V2) mV ∆ACC Control Limits for ∆ACC Control = V2 – V1 120 – 250 Dynamic APC Tap of R to GND 1 – 12 Pin Connection Diagram Hue Control 1 16 ACC Output OSC Output 2 15 ACC Output OSC Output 3 14 ACC Input Horiz Key Pulse Input 4 13 APC Input GND 5 12 APC Output OSC Input 6 11 APC Output OSC Feedback Loop 7 10 V (+) OSC Feedback Loop 8 9 16 9 1 8 N.C. .260 (6.6) Max .870 (22.0) Max .200 (5.08) Max .100 (2.54) .700 (17.78) .099 (2.5) Min V
