EQCO62R20.3/EQCO31R20.3
APPENDIX C: TYPICAL UPLINK CHARACTERISTICS
All measurements at VCC = 1.2V, Temp = +25ºC, data pattern = 8B/10B test pattern at 21 Mbps, typical R_amp and R_rise,
measured into 75Ω.
FIGURE C-1: SIGNAL TRANSMITTED BY LOW-SPEED DRIVER SHOWING BASLINE WANDER
DUE TO EXTERNAL 10 µH INDUCTOR AND FERRITE BEADS⁽¹⁾
1: Inductor and ferrite beads at the camera side of the link will double the baseline wandering. This is resolved
by the LF-Receiver in the EQCO62T20 chip.
