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.
