The IC is a low power ASK/FSK/GFSK Transceiver for the frequency bands 300-320, 415-495, 863-960 MHz. Bi-phase modulation schemes, like Manchester, bi-phase mark, bi-phase space and differential Manchester as well as NRZ are supported. The chip offers a high level of integration and needs only a few external components, like a crystal, several blocking capacitors and the necessary matching elements. The IF-filter is integrated but depending on the performance requirements an external ceramic IF-filter can be used. For low cost applications an external passive antenna switch configuration can be used. The device is qualified according to automotive quality standards and operates between -40 and +110 °C at supply voltage ranges of 3.0-3.6 Volts or 4.5-5.5 Volts. A fully integrated Sigma-Delta Fractional-N PLL Synthesizer, with high frequency resolution and a crystal oscillator as reference, generates the necessary frequencies for the power amplifier or down conversion mixers.

Summary of Features:

  • Operating temperature range -40 to +110°C
  • Supply voltage range 3.0 to 3.6 V or 4.5 to 5.5 V
  • Brownout detector
  • Integrated 4-wire SPI bus interface
  • 32-bit wide Unique ID on chip
  • On-chip temperature sensor
  • ESD protection +/- 2 kV on all pins (HBM)
  • PG-TSSOP-28 package

Target Applications:

  • Remote keyless entry (RKE)
  • Remote start applications
  • Passive Keyless Entry (PKE)
  • Security Alarm Systems
  • Automatic Meter Reading (AMR) and Infrastructure (AMI)
  • Home Automation
  • Remote Control
  • Sensor Networks
  • Short range radio data transmission
