Assuming a low capacitance, there are no particular impedance matching problems other than known with digital logic.
If its a direct "analog", high capacitance input, no PCB trace can actually match it. At best you can place the driver near to the
CCD and use a sufficient wide (e.g. 50 ohm) low inductance trace. If a longer trace cant be avoided, you can consider a
20 to 50 ohm trace and source side impedance matching.
For a detailed discussion, the actual device data should be known.
