Please let me know about two points below for DS100BR210.
※Evaluating DS100BR210EVK, 2.94Gbps, and cable are AWG-30 3m and AWG-26 6m(Total 9m)
-----------------------------------------------------------------------
①When increase EQ level(Pin setting), EQ Lebel: 9(EQA1=F, EQB1=0)is reduce effect.
Is EQ gain is not monotony increase?
Please see attached below;
※Horizontal line: EQ Gain
Vertical line: Upper(Non-emphasis), Middle(2.5dB emphasis), Lower(6dB emphasis)
For example, Upper/20dB is increase jitter, but Upper/23dB is reduce jitter.
②About below block diagram, I think that EQ-Gain is only EQ point, and output signal is amplitude from two output buffer, is it correct?
And, is there spec information of EQ spec graph(Horizontal: Frequency, Vertical: Gain) and buffer Gain?
