NTE1814 Integrated Circuit CMOS, Color Processing Circuit for VCR Description: The NTE1814 is a CMOS LSI integrated circuit in an 18–Lead DIP type package designed for use in VCR color signal processing circuits for VHS system video tape recorders. This device is used in configuration with the NTE1813 for color signal processing in 2, 4, and 6Hr modes in NTSC VCR systems. Features: D In Recording, a Video Color Signal can be Converted into a Low–Frequency Video Color Signal by AFC and REC APC. D In Playback, the Low–Frequency Color Signal can be Converted into the Original Video Color Signal on the Color Subcarrier Wave Frequency by PB APC and the Side Lock Detect Circuit. D The NTE1814 Contains the Following Functions: Rotary Circuit DPLL (Digital Phase Locked Loop) Circuit Side Lock Detect Circuit Field Start Inhibit Pulse Generating Circuit Burst Adjust Pulse Generating Circuit Burst Gate Pulse Generating Circuit Monostable Multivibrator Circuit Phase Comparator D Can be Miniaturized and Simplified with High Reliability D Low Power Dissipation: 15mW @ 5V Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Supply Voltage, VDD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.3 to +8.0V Input Voltage, VI . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.3V to VDD+0.3V Output Votage, VO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.3V to VDD+0.3V Operating Ambient Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –10° to +70°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –55° to + 125°C Recommended Operating Conditions: (VSS = 0V, TA = +25°C ±2°C unless otherwise specified) Parameter Symbol Test Conditions Supply Voltage VDD VCO Input Operating Frequency fVCO NTSC VCO Input Amplitude VVCO C cut (C = 1000pF) Sine Wave Input Min Typ Max Unit 4.5 5.0 5.5 V – 5.03 – MHz 0.3 0.5 – VP–P DC Electrical Characteristics: (VDD = 5V, VSS = 0V, TA = +25°C ±2°C, fVCO = 5.03MHz (NTSC) unless otherwise specified) Parameter Symbol Test Conditions Min Typ Max Unit Supply Current IDD No Load – – 3 mA Power Dissipation Ptot No Load – – 15 mW Input Terminal 1 PGI, SYN VIH1 3.5 – VDD V VIL1 VSS – 1.5 V Input Terminal 2 SCM, PN, NREC, BERR, TPB (with a Pull–Low Resistance) VIH2 3.5 – VDD V VIL2 VSS – 1.5 V – – 300 µA VIH3 3.5 – VDD V VIL3 VSS – 1.5 V – – –300 µA IIH2 Input Terminal 3 NCLR (with a Pull–High Resistance) VI = 5V IIH3 VI = 0V Output Terminal 1 HP, PSSC IOH1 VOH = 3.5V –0.5 – – mA IOL1 VOL = 1.5V 0.5 – – mA Output Terminal 2 LOC, PCO, BADJ, BGP (3–Value Output) IOH2 VOH = 2.5V –2.5 –5.0 – mA IOL2 VOL = 2.5V 2.5 5.0 – mA – – ±5 µA Output Terminal 3 FSI ILeak2 VO = 5V, 0V (with a High Impedance) IOH3 VOH = 4.3V –0.5 – – mA IOL3 VOL = 0.7V 0.5 – – mA Pin Connection Diagram VDD 1 VCO Clock Input NTSC/PAL/SECAM Select Input (SCM) Horiz Pulse Output NTSC/PAL/SECAM Select Input (PN) Head Switch Pulse Input 2 18 Burst Gate Pulse Output 4 17 Special PB Select Input 16 Low Converting Color Subcarrier Wave Output 15 System Clear Input 5 14 Sync Signal Input 6 13 Field Start Inhibit Pulse Output 12 Burst Compensation Error Pulse Input 11 Rec/PB Select Input 3 Side Lock Detect Output 7 VSS 8 Phase Comparator Output 9 10 Burst Compensation Pulse Output 18 10 1 9 .762 (19.35) Max .338 (8.6) .187 (4.7) .070 (1.78) .700 (17.78) .135 (3.4)
