ASK/FSK TRANSCEIVER 915MHZ Description

The IC is a low power consumption single chip FSK/ASK Transceiver for half duplex low datarate communication in the 915MHz band. The IC offers a very high level of integration and needs only a few external components. It contains a highly efficient power amplifier, a low noise amplifier (LNA) with AGC, a double balanced mixer, a complex direct conversion stage, I/Q limiters with RSSI generation, an FSK demodulator, a fully integrated VCO and PLL synthesizer, a tuneable crystal oscillator, an onboard data filter, a data comparator (slicer), positive and negative peak detectors, a data rate detection circuit and a 2/3-wire bus interface. Additionally there is a power down feature to save battery power

Summary of Features

  • Low supply current (Is= 9mA typ. receive, Is = 13mA typ. transmit mode)
  • Supply voltage range 2.1 - 5.5V
  • Power down mode with very low supply current consumption
  • FSK and ASK modulation and demodulation capability
  • Fully integrated VCO and PLL synthesizer and loop filter on-chip with onchip crystal oscillator tuning
  • I2C/3-wire μController Interface
  • On-chip low pass channel select filter and data filter with tuneable bandwidth
  • Data slicer with self-adjusting threshold and 2 peak detectors
  • FSK sensitivity <-109dBm, ASK sensitivity <109dBm
  • Transmit power up to +13dBm
  • Self-polling logic with ultra fast data rate detection
