FUNCTIONAL DESCRIPTION

The VTBT5UF201 is a combination tuner and demodulator in one package. It is compatible with North American NTSC television broadcast signals. An internal Phase-Locked Loop circuit performs all of the required tuning functions. The tuner and demodulator blocks are internally connected. An IF sample port is provided for monitoring the signal level or frequency characteristics of the recovered IF signal. The RF connector is mounted on the end of the housing so that the smallest possible area is used on the rear panel of a final installation. Demodulated audio, video, and AFT outputs are provided. The AFT Mute function is available as well. The AGC control line from the demodulator to the tuner is not accessible to the system designer.
