Pin Diagram
UHF ASK/FSK Transmitter:
• Conforms to US FCC Part 15.231 regulations and
• VCO phase locked to quartz crystal reference;
• Integrated crystal oscillator and VCO requiring
• Crystal frequency divide by 4 available (CLKOUT)
• Frequency range set by crystal: 310 – 480 MHz
• ASK Data rate: 0 – 40 Kbps
• FSK through crystal pulling allows modulation at
• Adjustable output power: +2 dBm to -12 dBm in
• Differential output configurable for single or
• Power amplifier automatically disabled until after
