Part Number: TLV3011B
Other Parts Discussed in Thread: TL103W, TSM102, REF3325

Hi team,

As title, do we have function similar but REF voltage level is 2.5V?

Thanks

No; you need to divide down the input voltage.

The most similar device with a 2.5 V reference would be the TL103W(B).

Hi Paul,

We did have the TSM102 with an adjustable reference, but it is going end-of-life.

Unfortunately, the current devices have references of 1.242V, 1.2V, 0.5V, 0.4V and 0.2V.

Is there a specific reason for 2.5V?

Paul,

Customer plan to develop one test equipment in OSFP fiber module application, see below block to know more detail.

There is comparator used in HOST side, see below green circle.

Thanks

There is no integrated device for this. You have to divide down the INT/RSTn signal, or generate the 2.5 V reference with a divider.

Paul,

I've seen the best implementation for the host side is to use an external reference part such as the REF3325 or create it from a resistor divider as Clemens said.
