Greetings Shinichi-San,

1). I checked LMH0344 and we do not have CS pin. Could you please double check with the customer?

2). Also, LMH0344 is one of the older 3G SDI equalizer. The latest 3G SDI equalizer is LMH0324. Please note data sheet below. Please ask your customer to review this part's data sheet as well:

Hi Nasser,

Thank you for your reply.

I'm sorry, I mistakenly wrote CS.

The CD pin is correct.

Can you tell me how many ohms is when the CD pin is at L?

Regarding the LMH0324, I will share this with our customers.

I appreciate your great help and cooperation.

Best regards,

Shinichi

Hi Shinichi-San,

We expect this to be 200-ohm or less.

LMH0324 is a much newer device and it could be a good idea for the customer to consider this part as well.
