SX1230 Integrated Transmitter IC

Narrow/wideband 315MHz, 434MHz, 868MHz and 915MHz Band Transmitter - Now Available at DigiKey

Image of Semtech's SX1230 Integrated Transmitter IC Semtech's SX1230 is a fully integrated transmitter that can operate in the 315 MHz, 434 MHz, 868 MHz, and 915 MHz license 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 configurations and messages from an E2PROM in response to a user input.

Overview

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 300 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 V to 3.7 V range
  • Low phase noise (-95 dBc/Hz at 50 kHz) with automated PLL calibration
  • Fully integrated VCO and loop filter
  • On chip RC timer for timer/wake-up applications
  • Low battery detection
Applications
  • Remote keyless entry (RKE)
  • Remote control/security systems
  • Voice and data RF communication links
  • Process and building/home control
  • Active RFID
  • AMR/AMI platforms
