New BSFC-Series tuners use SHARP’s latest technology to provide
reception of either modulated analog or digital data streams. Four
different tuner models with varying performance characteristics can
be used as receivers for analog or digital video, and for data streams.

Each tuner’s local oscillator is phase-lock loop-tuned using a
3-wire serial bus. The conversion intermediate frequency is filtered
and provided on a pin at 479.5 MHz. In addition, IF ACG control
is provided.

Both horizontal and vertical (pictured) package styles are
available, along with a wide variety of SAW filters. Dual input
versions may be available upon request. Filter configurations not
shown in the model selection guide on back may also be available
