DESCRIPTION
The BSFH78G23 is an integrated single conversion tuner
and FM demodulator. It was designed for the reception
of analog signals. It has a single input and a combined
video and audio output. The input frequency range is
900 to 2,150 MHz. A 27/18 MHz switchable bandpass
filter is positioned at the first IF. Bandwidth selection is
made by applying an external voltage via an external pin.
A digital AFT output is provided for evaluation of receiver
system accuracy.
This tuner can be controlled by an internal three wire
PLL interface. A 1/256 prescaler is internal to this tuner
and provides the ability to interface with the PLL.
