Hello TI employees,
i'm wondering if i can use TS3L110 for multiplexing an demultiplexing of FSI and SPI interfaces.
Kind regards Ralf

We want to use the TS3l110 with the FSI interface of TMS320F28388D:
- So, it would be 3.3V C-MOS levels with a frequency of 50 MHz
- And for our pcb routing we need to know the impedance of the switch (sinle line and differential)
Kind regards Ralf
Hello Ralf,
The TS3L110 has a bandwidth of 500MHz and can pass voltage signals from 0 to 5.5V. It can reliably be implemented in your application.
The impedance of the switch is typically 4ohms.
Thanks,
Nir
Hello Nir,
thanks for your reply.
We are driving our FSI signals with a DSLVDS1047 and pass the LVDS signals over the TS3l110. So, i meant the impedances from a signal line (e.g. YA to IA0 or YA to IA1) to ground or between two signal lines (e.g. YA-IA0 to YB-IB0).
Kind regards Ralf
Hello Ralf,
The Ron (on resistance) of a multiplexer is the resistance across the switch, or in other words between the input and the output (YA to IAx).
This is the impedance of the switch.
Thanks,
Nir
