Semtech SX1230 Integrated Transmitter IC

Semtech SX1230 Integrated Transmitter IC is a fully integrated transmitter that operates in 315, 434, 868 and 915MHz license free ISM bands. The SX1230 features bit rates up to 600kbits/sec with +17dBm to -18dBm programmable output power. The transmitter has two operation modes, a conventional MCU controlled mode and a "stand-alone" mode. These modes enable the SX1230 to download configuration and messages from an E2PROM in response to a user input. The stand-alone mode makes the SX1230 ideal for miniaturized or low cost remote keyless entry (RKE) applications. The SX1230 also offers the unique advantage of narrow-band and wideband communication in a range of modulation formats.

FEATURES
