Question about SITE SI003AB

[CCD lab]

Dear Sir,
Our PI 1024*1024 TKB CCD(SITe 1024X1024 SI-003A CCD chip) has problem now.
On image, its CTE is very poor. In this camera, a EL7182 is used to drive
the RGd,(d is the output) through a resistor of 191 ohm. We think the RGd is
not clocked properly. The time delay of this pin is about 700 ns, that means
the equivalent capacitor of RGd is about 1300pF! Is there anything wrong
with this pin?

On the other hand, the output of EL7182 is a very good pulse with a width of
600ns and an amplitude of 12V, then it is input into the 191ohm resistor.
After that, the waveform changes into a triangle, with a amplitude of 10.5V
and width of 1500ns. Does this pulse work well?

Thank you.
