23. EZRadioPRO
240–960 MHz Transceiver
Si1010/1/2/3/4/5 devices include the EZRadioPRO family of ISM wireless transceivers with continuous fre-
quency tuning over 240–960 MHz. The wide operating voltage range of 1.8–3.6 V and low current con-
sumption makes the EZRadioPRO an ideal solution for battery powered applications.
The EZRadioPRO transceiver operates as a time division duplexing (TDD) transceiver where the device
alternately transmits and receives data packets. The device uses a single-conversion mixer to downcon-
vert the 2-level FSK/GFSK/OOK modulated receive signal to a low IF frequency. Following a programma-
ble gain amplifier (PGA) the signal is converted to the digital domain by a high performance ADC
allowing filtering, demodulation, slicing, and packet handling to be performed in the built-in DSP increasing
the receiver’s performance and flexibility versus analog based architectures. The demodulated signal is
then output to the system MCU through a programmable GPIO or via the standard SPI bus by reading the
64-byte RX FIFO.
A single high precision local oscillator (LO) is used for both transmit and receive modes since the transmit-
ter and receiver do not operate at the same time. The LO is generated by an integrated VCO and Frac-
tional-N PLL synthesizer. The synthesizer is designed to support configurable data rates, output frequency
and frequency deviation at any frequency between 240–960 MHz. The transmit FSK data is modulated
directly into the data stream and can be shaped by a Gaussian low-pass filter to reduce unwanted
spectral content.
The Si1010’s PA output power can be configured between –1 and +20 dBm in 3 dB steps, while the
Si1012/3/4/5's PA output power can be configured between –8 and +13 dBm in 3 dB steps. The PA is sin-
gle-ended to allow for easy antenna matching and low BOM cost. The PA incorporates automatic ramp-up
and rampdown control to reduce unwanted spectral spreading. The +20 dBm power amplifier of the
Si1010/1 can also be used to compensate for the reduced performance of a lower cost, lower performance
antenna or antenna with size constraints due to a small form-factor. Competing solutions require large and
expensive external PAs to achieve comparable performance. The EZRadioPRO transceivers support fre-
quency hopping, TX/RX switch control, and antenna diversity switch control to extend the link range and
improve performance.
The EZRadioPRO peripheral also controls three GPIO pins: GPIO_0, GPIO_1, and GPIO_2. See Applica-
tion Note “AN415: EZRadioPRO Programming Guide“ for details on initializing and using the EZRadioPRO
peripheral.
