Description

The SX1230 is a fully integrated transmitter which canoperate in the 315, 434, 868 and 915 MHz licence free ISM bands.

The transmitter has two modes of operation, a conventional MCU controlled mode and a ‘stand-alone’ mode which enables the SX1230 to download configuration and messages from an E2PROM in response to a user input.Stand-alone mode makes the SX1230 ideal for miniaturized or low cost remote keyless entry (RKE) applications. It also offers the unique advantage of narrow-band and wide-band communication in a range of modulation formats.

The SX1230 offers high RF output power and channelized operation suited for the European (ETSI EN 300-220-1), North American (FCC part 15.231, 15.247 and 15.249) and Japanese (ARIB T-67) regulatory standards.

Features

  • +17 dBm to -18 dBm Programmable output power.
  • Bit rates up to 600 kbits / sec.
  • FSK, GFSK, MSK, GMSK and OOK modulation.
  • Stand-alone mode: No need for a host MCU.
  • Consistent RF performance over a 1.8 to 3.7 V range.
  • Low phase noise (-95 dBc/Hz at 50 kHz) with automated PLL calibration and fully integrated VCO and loop filter.
  • On chip RC timer for timer / wake-up applications.
  • Low battery detection.

Typical applications

  • Remote Control / Security Systems
  • Voice and Data RF Communication Links
  • Active RFID
  • Remote Keyless Entry (RKE)
  • AMR / AMI Platforms
  • Process and building / home control
