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:
