Other Parts Discussed in Thread: LMH0341, LMH0340, DS32EL0421, DS32EL0124

Hi Team,

Our customer will replace LMH0340 to DS32EL0421 and LMH0341 to DS32EL0124.

There are several NC pins for DS32EL0421/0124. Would there be any problem for connecting these NC pin to GND or VCC or some voltage level ?

I'm asking this because some of the functional pins of LMH0340/0341 are NC pins for DS32EL0421/0124.

Best Regards,
Kawai

    Kawai-San,

    Thanks for your continued support on these products.

    Please allow me to suggest to use DS32EL0421 and EL0124 data sheet and leave these NC. LMH0340/341 are closely coupled with the SDI FPGA but on the other hand DS32EL0124/0421 are wide band ser/des and customer has more flexibility. If you like, please allow us to review the customer schematic when they are ready.
