Pin Diagram:
UHF ASK/FSK Transmitter:
• Integrated crystal oscillator, VCO, loop filter and
power amp for minimum external components
• ASK data rate: 0 – 40 Kbps
• FSK data rate: 0 – 40 Kbps by crystal pulling
• Output power: +10 dBm to -12 dBm in 4 steps
• Adjustable transmitter power consumption
• Transmit frequency set by crystal multiplied by 32
• VCO phase locked to quartz crystal reference;
allows narrow band receivers to be used to
maximize range and interference immunity
• Crystal frequency divide by 4 available (REFCLK)
• Used in applications conforming to US FCC Part
15.231 and European EN 300 220 regulations
Applications:
• Automotive Remote Keyless Entry (RKE) systems
• Automotive alarm systems
• Community gate and garage door openers
• Burglar alarm systems
• Building access
• Low power telemetry
• Meter reading
• Tire pressure sensors
• Wireless sensors
