Specified as ac parameter to include sensitivity to overshoot, undershoot and reflection.
tbit is 1/10 the pixel time, tpix
§ tpix is the pixel time defined as the period of the RxC input clock. The period of ODCK is equal to tpix in 1-pixel/clock mode or 2tpix when in
2-pixel/clock mode.
Measured differentially at 50% crossing using ODCK output clock as trigger.
# Rise and fall times measured as time between 20% and 80% of signal amplitude.
|| Data and control signals are : QE[23:0], QO[23:0], DE, HSYNC, VSYNC and CTL[3:1]
kLink active or inactive is determined by amount of time detected between DE transitions. SCDT indicates link activity.
