1.0 SRF310 Introduction
The SRF310 receive/transmit module (RTM) is based on a single-chip radio frequency (RF)
transceiver integrated circuit (RFIC), an Atmel AT86RF212B. The SRF310 RTM is intended to
be integrated into Cervis Inc. products, providing a wireless RF connectivity option.
The SRF310 RTM operates in the 915 MHz ISM band, using spread spectrum modulation
with a maximum conducted RF transmit power of +22.07dBm (161mW) at the antenna port.
The RFIC generates RF signals compliant with the Zigbee standard, IEEE 802.15.4-2006.
The spread spectrum technique is direct sequence (DSSS), the modulation method is binary
phase shift keying (BPSK).
The RFIC has internal control registers that the host application can access via a serial
peripheral (SPI) bus. These registers control all aspects of how the RFIC is used, which must be
compliant with all applicable rules and regulations.
The SRF310 RTM is interoperable various other Cervis Inc. RTMs that use the same
modulation and message data structure. Interoperability with non-Cervis RTMs, while possible,
is not supported.
The SRF310 RTM is most commonly applied in half-duplex master/slave systems: the master
transmits a message to a slave, the slave transmits a reply to the master. Other operating
modes are possible, provided that applicable rules and regulations are not violated.
The SRF310 RTM is realized as a solder-down leadless PCB module. The Type 4 form factor
is a unique proprietary mechanical design.
