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))
