As a TXCO enable, the pin is an output on power up and driven logic high. During hibernate low-power mode, the pin is in a Hi-Z state but is pulled down for SOP mode to disable TCXO. Because of the SOP functionality, the pin must be used as an output only. (3) Output Only (4) This pin is reserved for WLAN antenna selection, controlling an external RF switch that multiplexes the RF pin of the CC3130x device between two antennas. These pins must not be used for other functionalities. CC3130 SWRS227 – MARCH 2020 www.ti.com 12 Submit Document Feedback Copyright © 2020 Texas Instruments Incorporated |
