Si4032/31/30
ISM Transmitter
Description
Silicon Laboratories’ Si4032/31/30 highly integrated, single chip
wireless ISM transmitter is part of the EZRadioPRO™ family. The
EZRadioPRO family includes a complete line of transmitters,
receivers, and transceivers allowing the RF system designer to
choose the optimal wireless part for their application.
The Si4032/31 offers advanced radio features including
continuous frequency coverage from 240–930 MHz and
adjustable output power of up to +20 dBm with the Si4032. The
Si4030 offers frequency coverage from 900 to 960 MHz to support
the Japanese frequency bands. The Si4032 delivers a maximum
output power of +20 dBm programmable from +11 to +20 dBm in
3 dB steps. The Si4031/30 delivers a maximum output power of
+13 dBm programmable from –8 to +13 dBm. The Si4032/31/30’s
high level of integration offers reduced BOM cost while simplifying
the overall system design. The Si4032’s Industry leading +20 dBm
output power ensures extended range and improved link
performance.
Additional system features such as an automatic wake-up timer,
low battery detector, 64 byte TX FIFO and automatic packet
handling reduce overall current consumption and allow the use of
lower-cost system MCUs. An integrated temperature sensor,
general purpose ADC, power-on-reset (POR), and GPIOs further
reduce overall system cost and size.
The transmitter supports automated packet construction, allowing
data to be streamed from the TX FIFO without external MCU
support. The PA is single-ended to allow for easy antenna
matching and low BOM cost. The digital transmit modulation and
automatic PA power ramping ensure precise transmit modulation
and reduced spectral splatter, ensuring compliance with FCC and
ETSI regulations. The Si4030 is designed to ensure compliance
with ARIB regulations. The Si4032/31/30 is designed to work with
an MCU, crystal, and a few passives to create a very low-cost
system. Voltage regulators are integrated on-chip, which allows for
a wide range of operating supply voltage conditions from +1.8 to
+3.6 V.
