ML13156
Wideband FM IF System
Legacy Device: Motorola MC13156
The ML13156 is a wideband FM IF subsystem targeted at high per-
formance data and analog applications. The ML13156 has an onboard
grounded collector VCO transistor that may be used with a fundamen-
tal 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 preci-
sion data shaper has a hold function to preset the shaper for fast recov-
ery of new data.
