NTE1827

NTE1827 Integrated Circuit VIF & SIF Circuit for TV/VCR Description: The NTE1827 is an IC containing the VIF section and SIF section on a single chip in the 20–Lead DIP package. The use of the small–sized package serves to make VCR tuner units smaller. Functions: D VIF section: VIF AMP, Video Det, Peak IF AGC, B/W Noise Canceller, RF AGC, AFT, Video Mute. D SIF section: SIF Limiter Amp, FM Det, SND Mute. Features: D High–Gain VIF Amp Requiring No Preamp D Non–Adjusting can be Attained by using a Ceramic Discriminator because of FM Detection being Quadrature Detection. D Possible to Mute Video, Sound for VCR. D Small–Sized Package. D Minimum Number of External Parts Required. D Operates from 9V Supply Voltage Operating Characteristics: (TA = +25°C, VCC = 12V, fp = 58.75MHz, fs = 54.25MHz (VIF)) Parameter Total Circuit Current Maximum RF AGC Voltage Minimum RF AGC Voltage Quiescent Video Output Voltage Input Sensitivity AGC Range Maximum Allowable Input Video Output Amplitude Output S/N Carrier Leakage Maximum AFT Voltage Symbol I17 VIOH VIOL V11 Vi GR Vimax Vo(16) S/N CL VIIH fm = 400Hz 40%AM, Vo = 0.8Vp–p fm = 15kHz 78%AM, Vo = ±1dB fm =15kHz 78%AM, VO = ±1dB Vi = 10mVrms, fm = 15kHz 78%AM Vi = 10mVrms CW Vi = 100mVrms, fm = 15kHz 78% AM Vi = 10mVrms SWEEP Test Conditions Min 44 8.5 – 4.5 30 60 100 1.9 47 50 11 Typ 55 9.0 – 6.5 36 68 – 2.2 55 57 11.5 Max 73 9.5 0.5 7.0 42 – – 2.5 – – – Unit mA V V V dBu dB mVrms Vpp dB dB V Operating Characteristics (Cont’d): (TA = +25°C, VC...
