Part Number: TXS02324 Other Parts Discussed in Thread: TCA9803 , Tool/software: Hey,
I'm using the TCA9803 to buffer the I2C signal from baseband to the TXS02324.
The software department requests the HW-ID and gets a plausible answer. However, after…
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…
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?
sorry I mean. can we use txs02324 as a dual sim card multiplexer using only SDA, SCL and VDDIO pins on it? because in our system we have pin limitations
Hi Shreyas, Thanks for you rebply. About my question and your reply, Q: "The System default would start in 1.8V mode, but while the baseband is configuring in 2.95V, there is lack of communication between the baseband and the SIM card, so does the TXS02324…
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?
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…
