Input Clock Requirements
The input data clock, ClockIn, should be a free running signal with a maximum frequency of 40 MHz. It should
have a 50% duty cycle ( 10%). It is suggested that the device providing data to the KSC-3000 produce data on the
rising edge of the clock but then provide an inverted clock to the KSC-3000 ClockIn pin. This provides large timing
margins for setup and hold times, provided the clock and data signals are produced at the same time and location
with similar path lengths to minimize skew. A similar method is used at the red, green, and blue data outputs of the
KSC-3000. The data at the outputs is changed on the rising edge of ClockIn but the output clock, ClockOut, is an
inverted version of this clock to provide increased timing margins at the receiving device and to account for signal
skew.
