Hello community,
I am a student of electrical engineering and in the course of a laboratory I
am currently designing a serdes chip and looking for an adequate interface
for the I/Os.
Power dissipation an chip space are the most relevant aspects. What I do is
a 10Gbit/s to 1 Gbit/s deserializing. On the input I am using LVDS signals,
so what would be an appropriate signalling on the output for 1Gbit/s
signals? Is it possible to transmit 1 Gbit/s single ended or do I need to
use differential signalling? Unfortunately that means double the pad number
and thus double chip space, but chip space is expensive.
Because the supply budget is limited I want a minimum on power dissipated at
the output buffers. What transmission standard would be advisable in that
respect?
Thank you very much in advance
