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.
Applications for the ML13156 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)
• Operating Temperature Range – TA = –40 to +85°C
