DATASHEET
SX1230 - Integrated Transmitter IC
Narrow/wideband 315 MHz, 434 MHz 868 MHz and 915 MHz band Transmitter
GENERAL DESCRIPTION
The SX1230 is a fully integrated transmitter which can
operate 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.
