11 / 26 page Si4356 Rev 1.2 11 3. Device Configuration The Si4356 is configured for operation using the four configuration selector pins (SEL0 – SEL3). These pins will be connected to one of four possible inputs: GND, VDD, RX DATA/OUT1 (pin 14), or OUT0 (pin 12). Refer to the tables below for how these pins should be connected for the desired configuration. SEL0 and SEL1 may be connected to VDD, GND, or OUT1 to choose desired frequency. Note that a 10 k resistor should be inserted between SEL1 and OUT1 when SEL1 is mapped to OUT1. See Table 9 for frequency settings. SEL2 and SEL3 may be connected to VDD, GND, or OUT1 to choose desired modem configuration. See Table 10 for basic configurations. Note that a 10 k resistor should inserted between SEL2 and/or SEL3 and GND when SEL2 and/or SEL3 are mapped to GND. Table 9. Frequency Selection SEL0 SEL1 Frequency (MHz) GND VDD 433.92 VDD VDD 315.00 OUT1 VDD 434.15 GND OUT1 867.84 VDD OUT1 868.30 OUT1 OUT1 917.00 Table 10. Basic Configuration Config.
