NTE875
Integrated Circuit
Video IF Amplifier/PLL Detector System
Description:
The NTE875 is a complete video IF signal processing system on a single 28–Lead DIP type package.
This device contains a 5–stage gain–controlled IF amplifier, a PLL synchronous amplitude detector,
self–contained gated AGC, and a switchable AFC detector. The increased flexibility of the NTE875
makes it suitable for a wide variety of television applications where high quality video or sound carier
recovery is required. These include home receiver video IFs, cable and subscription TV decoders,
and parallel sound IF/intercarrier detector systems. Typical operating frequencies are 38.9MHz,
45.75MHz, 58.75MHz, and 61.25MHz.
Features:
D Low Differential Gain and Phase
D IF and Detector pin Compatible with NTE878 (Discontinued)
D Common–Base IF Inputs for SAW Filters
D True Synchronous Video Detector using PLL (Phase Lock Loop)
D Excellent Stability at High System Gains
D Noise–Average Gated AGC System
D Uncommitted AGC Comparator Input
D Internal AGC Gate Generator
D Superior Small–Signal Detector Linearity
D AFC Detector with Adjustable Output Bias
D 9MHz Video Bandwidth
D Reverse Tuner AGC Output
