WIDEBAND FM IF
SYSTEM FOR DIGITAL AND
ANALOG APPLICATIONS
The MC13156 is a wideband FM IF subsystem targeted at high
performance data and analog applications. Excellent high frequency
performance is achieved at low cost using Motorola’s MOSAIC 1.5 bipolar
process. The MC13156 has an onboard grounded collector VCO transistor
that may be used with a fundamental or overtone crystal in single channel
operation or with a PLL in multichannel operation. The mixer is useful to
500 MHz and may be used in a balanced–differential, or single–ended
configuration. The IF amplifier is split to accommodate two low cost
cascaded filters. RSSI output is derived by summing the output of both IF
sections. A precision data shaper has a hold function to preset the shaper for
fast recovery of new data.
