NOTES:

4. t(pixel) is the pixel time defined as the period of the TXC output clock. The period of IDCK is equal to t(pixel).

5. Rise and fall times are measured as the time between 20% and 80% of signal amplitude.

6. Measured differentially at the 50% crossing point using the IDCK+ input clock as a trigger.

7. Relative to input clock (IDCK).
