UHF FM/AM Transmitter
The MC13176 is a one chip FM/AM transmitter subsystem designed for
AM/FM communication systems. It include a Colpitts crystal reference
oscillator, UHF oscillator, ÷32 prescaler and phase detector forming a
versatile PLL system. Targeted applications are in the 260 to 470 MHz band
and the 902 to 928 MHz band covered by FCC Title 47; Part 15. Other
applications include local oscillator sources in UHF and 900 MHz receivers,
UHF and 900 MHz video transmitters, RF Local Area Networks (LANs), and
high frequency clock drivers. The MC13176 offers the following features:
• UHF Current Controlled Oscillator
• Uses Easily Available 3rd Overtone or Fundamental Crystals for
Reference
• Fewer External Parts Required
• Low Operating Supply Voltage (1.8 to 5.0 Vdc)
• Low Supply Drain Currents
• Power Output Adjustable (Up to 10 dBm)
• Differential Output for Loop Antenna or Balun Transformer Networks
• Power Down Feature
• ASK Modulated by Switching Output On and Off
• fo = 32 x fref

2. Pins 5, 10 & 15 are ground and connected to VEE which is the component/DC ground plane
2. side of PCB. These pins must be decoupled to VCC; decoupling capacitors should be placed
