**The ML13156 is a wideband FM IF subsystem targeted at high performance

data and analog applications. The ML13156 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.**

Applications for the ML13156 include CT–2, wideband data links and other radio systems utilizing GMSK, FSK, or FM modulation.
