TXS02326 具有转换器的双电源待机 SIM 卡多路复用器扩展器
The TXS02326 is a complete dual-supply standby Smart Identity Module (SIM) card solution for interfacing wireless baseband processors with two individual SIM subscriber cards to store data for mobile handset applications. It is a custom device which is used to extend a single SIM/UICC interface to be able to support two SIMs/UICCs.
The device complies with ISO/IEC Smart-Card Interface requirements as well as GSM and 3G mobile standards. It includes a high-speed level translator capable of supporting Class-B (2.95 V) and Class-C (1.8 V) interfaces, two low-dropout (LDO) voltage regulators that have output voltages that are selectable between 2.95-V Class-B and 1.8-V Class-C interfaces, an integrated "fast-mode" 400 kb/s "slave" I2C control register interface for configuration purposes, a 32-kHz clock input for internal timing generation, a shutdown input and a comparator input detecting battery pack removal to safely power-down the two SIM cards, each equipped with two programmable debounce counter
