LMH1218: Need Part number for 12G dual output channel fiber transmitter

Hi Malav,

Please consider LMH1226. This part is pin and register compatible with the LMH1219 that you are using and it can be used for this application. Here is a link to this part's data sheet:

Also, given you are using both LMH1219 and LMH1226, can you please send me a block diagram of the overall application? I am trying to see how we can optimize different devices usage for this design.

Hello Nasser,

LMH1219 is for fiber receiver. But we have require fiber transmitter for that we have used LMH1218 which take 12G input from FPGA and give you single channel fiber transmitter,  but we need two fiber transmitter output. So Could you suggest compatible part number which one having dual fiber transmitter? 

Here find the screenshot of the our requirement block diagram. 

Hello Nasser,

So I can used LMH1226 as below: Right? Both the outputs of the LMH1226 IC drive the optical module for 12G. is it? 

Thank you.
