Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: TXS02324 Are there any non-obvious issues when nesting the TSX02324 to build a 4:1 mux? Or should we build it out of discrete muxes instead?
Part Number: TXS02324 Hi E2E,
The datasheet indicates that there are internal pull-up/ pull-down resistors on the SIM IO pins as listed below.
1. Do I need to add extra pull-up resistors for SIMIO, SIM1IO, SIM2IO?
2. If the extra pull up resistors are…
Part Number: TXS02324 Hi E2E,
1. The power domain of Pin9~17 is refer to VDDIO(1.7V~3.3V). But the VIH(Max) of these pins is only 1.9V , does it means that these pins only support 1.8V(Class C) input voltage? If baseband could supply 3V VDDIO(Class B)…
Part Number: TXS02324 Other Parts Discussed in Thread: TXS02326A Hi E2E,
Could TXS02324 detect SIM Card plugin or not?
Which register will show the status?
Part Number: TXS02324 there is description about SIM card in datasheet, it can support GSM and 3G standard SIM card, how about 4G and LTE ?
many thanks
Eli,
For the TXS02324, an I2C register write is required to disable both of its LDOs, VSIM1 and VSIM2. This is noted in the application information section of the datasheet. There is no external control pin that can be used to enable/disable the LDOs…
