Description
Silicon Labs Si4362 devices are high-performance, low-current receivers
covering the sub-GHz frequency bands from 142 to 1050 MHz. The
radios are part of the EZRadioPRO® family, which includes a complete
line of transmitters, receivers, and transceivers covering a wide range of
applications. All parts offer outstanding sensitivity of –126 dBm while
achieving extremely low active and standby current consumption. The
60 dB adjacent channel selectivity with 12.5 kHz channel spacing
ensures robust receive operation in harsh RF conditions, which is
particularly important for narrowband operation. RX current of 10 mA
coupled with extremely low standby current and fast wake times ensure
extended battery life in the most demanding applications. The devices are
compliant with all worldwide regulatory standards: FCC, ETSI, and ARIB.

Notes:
1. All specification guaranteed by production test unless otherwise noted. Production test conditions and max limits are
listed in the “Production Test Conditions” section in "1.1. Definition of Test Conditions" on page 11.
2. For applications that use the major bands covered by Si4362, customers should use those parts instead of Si4362.
3. Default API setting for modulation deviation resolution is double the typical value specified.
4. Guaranteed by qualification. Qualification test conditions are listed in the "Qualification Test Conditions" section in "1.1.
Definition of Test Conditions" on page 11.

1.1. Definition of Test Conditions
Production Test Conditions:
TA = +25 °C.
VDD = +3.3 VDC.
External reference signal (XOUT) = 1.0 VPP at 30 MHz, centered around 0.8 VDC.
Production test schematic (unless noted otherwise).
All RX input levels are referred to the input of a tuned balun connected to the RX input pins of the Si4362.
Qualification Test Conditions:
TA = –40 to +85 °C (Typical TA = 25 °C).
VDD = +1.8 to +3.6 VDC (Typical VDD = 3.3 VDC).
Using RX reference design or production test schematic.
All RF input and output levels referred to the pins of the Si4362 (not the RF module).
