Si4356 Si4356 STANDALONE SUB-GHZ RECEIVER Features Pin configurable Low RX Current = 12 mA Frequency range = 315917 MHz Low standby current = 50 nA Supply Voltage = 1.83.6 V Max data rate = 120 kbps Receive sensitivity = Automatic gain control (AGC) Up to 113 dBm System clock output Modulation Low BOM (G)FSK 20-pin 3x3 mm QFN package OOK Applications Remote control Home automation Home security and alarm Industrial control Pin Assignments Garage and gate openers Sensor networks Remote keyless entry Health monitors Description GND 1 20 19 18 17 16 GND RST 2 15 SEL1 Silicon Laboratories Si4356 is a pin-strap configurable, low current, RXp 3 14 RX DATA / OUT1 sub-GHz EZRadio receiver. With no external MCU control needed, the GND Si4356 provides a true plug-and-play receive option. Excellent sensitivity RXn 4 13 STBY up to 113 dBm allows for a longer operating range, while the low current NC 5 12 MSTAT / OUT0 consumption of 12 mA active and 50 nA standby provides for superior GND 6 7 8 9 10 11 SEL0 battery life. The Si4356 provides receive data as well as a system clock output for use by an external microcontroller or decoder. 20-pin QFN (Top View) Patents pending Rev 1.2 1/16 Copyright 2016 by Silicon Laboratories Si4356 Not Recommended for New Designs SEL3 VDD VDD SEL2 GND XIN CLK OUT XOUTSi4356 Functional Block Diagram XIN XOUT RST Synthesizer CLK OUT 30MHz XO Rx Chain STBY RXp LNA PGA ADC Rx Modem RX DATA / OUT1 RXn MSTAT / OUT0 Configuration Decoder SEL1 SEL2 SEL3 VDD GND SEL0 2 Rev 1.2 Not Recommended for New Designs
