Description
Silicon Laboratories' Si4356 is a pin-strap configurable, low current,
sub-GHz EZRadio® receiver. With no external MCU control needed, the
Si4356 provides a true plug-and-play receive option. Excellent sensitivity
up to –113 dBm allows for a longer operating range, while the low current
consumption of 12 mA active and 50 nA standby provides for superior
battery life. The Si4356 provides receive data as well as a system clock
output for use by an external microcontroller or decoder.
