Semtech SX1230 Integrated Transmitter IC
Semtech SX1230 Integrated Transmitter IC is a fully integrated transmitter that operates in the 315MHz, 434MHz, 868MHz, 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 IC to download configuration and messages from an E2PROM in response to user input. The stand-alone mode makes the SX1230 ideal for miniaturized or low-cost remote keyless entry (RKE) applications. The Semtech SX1230 Integrated Transmitter IC also offers the unique advantage of narrow-band and wideband communication in a range of modulation formats.
