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.

Applications for the MC13156 include CT–2, wideband data links and other radio systems utilizing GMSK, FSK or FM modulation.

• 2.0 to 6.0 Vdc Operation

• Typical Sensitivity at 200 MHz of 2.0 µV for 12 dB SINAD

• RSSI Dynamic Range Typically 80 dB

• High Performance Data Shaper for Enhanced CT–2 Operation

• Internal 330 Ω and 1.4 kΩ Terminations for 10.7 MHz and 455 kHz Filters

• Split IF for Improved Filtering and Extended RSSI Range

• 3rd Order Intercept (Input) of –25 dBm (Input Matched)
