Si4030/31/32 RF Transmitter

The Si4030/31/32 transmitters are members of the EZRadioPRO® product family. While retaining all the attractive features of the earlier products such as high integration, low cost, flexibility, low BOM and easy design-in, they target more sophisticated applications and offer several enhanced parameters and features including output power up to +20 dBm.

The transmitters provide continuous frequency coverage from 240 - 960 MHz. When used in any one of the standard ISM bands that fall within this range, the devices comply with the relevant FCC and ETSI requirements if a properly designed antenna matching and filter network is used. Apart from this, only a 30 MHz crystal and supply bypass capacitors are necessary as external components, making the devices ideal for high-volume production in applications where size and cost are important. At the application level, built-in features such as wake-up timer, low battery detector, transmit data FIFO, power-on reset circuit and general-purpose digital I/Os simplify the task of the system designer and allow the use of cost-effective microcontrollers.

Features

  • Fully integrated: low BOM, easy design-in, no production alignments
  • Wide range of operating conditions: supply voltage, temperature, frequency
  • Fast settling, high resolution synthesizer: quick turn-on, fast frequency hopping capability
  • FSK modulation with accurate, programmable frequency deviation
  • Optional watch crystal connection for more accurate timing
  • Alternative modes: GFSK for reduced occupied bandwidth, OOK for reduced consumption
  • Built-in 64-byte data FIFO: can hold entire packet with retransmit capability
  • Automatic preamble, packet header and CRC generation options
 

Applications

  • Remote control
  • Home security and alarm
  • Wireless keyboard/mouse and other PC peripherals
  • Wireless toys
  • Remote keyless entry
  • Health monitors
  • Industrial control
  • Telemetry
  • Personal/patient data logging
  • Remote automatic meter reading
  • Home automation
  • Sensor networks

Technologies

  • Highly efficient power amplifier with programmable output power
  • Programmable, very low current wake-up timer and battery voltage detector
