Given a data rate or clock rate, how to calculate bit time of any signal/interface?
As per what I know, bit time = 1/data rate. Is it correct?
I got a little confused when I could not calculate the TBIT values (and eventually skew) in the following:
This time difference, also known as intra-pair skew, is specified by HDMI for a receiver with 0.4 · TBIT for a TMDS clock rate of 225 MHz, which translates to 178 ps maximum. For an HDMI transmitter the specification calls for 0.15 · TBIT for a TMDS clock rate of 225 MHz, which translates to 66 ps maximum.
Am I missing something here?
Any help is appreciated.
