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))
