Order this document by MC13175/D MC13175 UHF FM/AM Transmitter The MC13175 and MC13176 are one chip FM/AM transmitter subsystems designed for AM/FM communication systems. They include a Colpitts crystal reference oscillator, UHF oscillator, ÷ 8 (MC13175) or ÷ 32 (MC13176) prescaler and phase detector forming a versatile PLL system. Targeted applications are in the 260 to 470 MHz band and 902 to 928 MHz band covered by FCC Title 47; Part 15. Other applications include local oscillator sources in.

Targeted applications are in the 260 to 470 MHz band and 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 MC13175/76 offer the following features: • UHF Current Controlled Oscillator MC13176 UHF FM/AM TRANSMITTER SEMICONDUCTOR TECHNICAL DATA • • • • • • • • • 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 (MC13175) fo = 8 x fref; (MC13176) fo = 32 x fref D SUFFIX PLASTIC PACKAGE CASE 751B (SO–16) 16 1 Figure 1.

Pins 5, 10 & 15 are ground and connected to VEE which is the component/DC ground plane side of PCB. These pins must be decoupled to VCC; decoupling capacitors should be placed as close as possible to the pins. The crystal oscillator circuit may be adjusted for frequency with the variable inductor (MC13175); recommended source is Coilcraft “slot seven” 7mm tuneable inductor, Part #7M3–821. 1.0k resistor. Shunting the crystal prevents it from oscillating in the fundamental mode.
