Hello Team

We are looking for SDI-3G Equalizer. following are my requirements

Speed: > 3Gbps

Input type: LVDS

Output Type: CML

I could not find the input and out signal type in datasheet of LMH1219 part. Is this part support to my application?

Could you please suggest me if any other parts available in TI with my requirements?

Regards

Hi Krupanand,

One option is the https://www.ti.com/product/DS30EA101

DS30EA101. It has a speed greater than 3 Gbps, specifies the required outputs in the datasheet, and is an equalizer. Does this meet your application requirements and do you have any more questions about the part?

Best,

Nick

Hi Krupanand,

Yes, but the outputs can be DC coupled and adapted to a CML receiver:

"The DS30EA101 output signals (OUT+ and OUT- ) are internally terminated 100Ω LVDS outputs. These outputs can be DC coupled to most common differential receivers."

See https://www.ti.com/lit/an/slla120/slla120.pdf

and https://www.ti.com/lit/an/scaa056/scaa056.pdf

Best,

Nick
