Part Number: TS3USB221


Hi Sir,

My customer is looking for a SPDT differential mux for the eARC application.

The mux device needs to meet the below condition, is the TS3USB221 suitable for this request?

1. The differential impedance at 100ohm+/-10%.

2. The signal dc bias is 4V.

3. The eARC spec as below.

    Hi Henry,

    Looking at the spec, it looks like the signal will max out at around 4.5V, that should be okay with this device. Differential impedance should be okay as well.

    What is the typical bandwidth? This device is spec'd for 1.1GHz, so as long as it is within that, it should be okay.

    Thanks,

    Ryan
