NTE7015 Integrated Circuit PLL SIF & VIF for TV & VCR Description: The NTE7015 is a semiconductor integrated circuit consisting of an IF signal processor suitable for color TV sets and VTRs with AV. The circuits include VIF amplifiers, video detector, VCO, APC detector, AFT, video equalizer, IF/RF AGC, SIF detector functions. Features: D Employment of a full synchronous detector circuit using PLL as video detector provides excellent DG, DP, 920kHz beat and cross color characteristics. D Usage of PLL−SPLIT method to obtain intercarrier by separating video IF and audio IF processing by VCO output provides good sound sensitivity and reduces buzz. In consumer sets, intercarrier is also available from the video detector output. D Built−in video equalizer suitable for VTRs and color TV sets equipped with video output terminals. D Employment of quadrature detector circuit for FM detection of audio IF requires no adjustment. Applications: TV sets, VTR tuners Recommended Operating Conditions: Supply voltage range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 to10V Rated supply voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9V Absolute Maximum Ratings: (TA = +25°C, permissible surge capacitance is 200pF, unless otherwise noted) Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14V Power Dissipation, PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1250mW Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −20 to+75°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −40 to +125°C Permissible surge (pin 8), Surge 8 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +200, − 150V Permissible surge (pin 9), Surge 9 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +200, −150V Permissible surge (other pins) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±200V Electrical Characteristics: (TA = +25°C, VCC = 9V, unless otherwise noted) Parameter Circuit Current (VIF) Video detector output DC voltage 1 Symbol Test Conditions Input Signal VIF SIF1 Test Conditions External Voltage (V) V20 V1 V6 Switch is set at 1.
