(1)
Timing parameters are specified by design and characterization and not tested in production.
(2)
CL is the effective external single-ended load capacitance between each output pin and ground.
(3)
IO refers to the LVDS buffer current setting; RL is the differential load resistance between the LVDS output pair.
(4)
Measurements are done with a transmission line of 100-
characteristic impedance between the device and the load.
(5)
Setup and hold time specifications take into account the effect of jitter on the output data and clock.
(6)
Data valid refers to logic high of +100 mV and logic low of
–100 mV.
