From a customer:
"I was looking in the TMS320C6712D data sheet for ECLKOUT specifications. The only spec’s that I found are on page 71 of SGUS055. These spec’s seem to be for ECLKOUT based on ECLKIN. In our case, we are using a 48 MHz oscillator attached to CLKIN. We use the PLL to multiply the 48 MHz by 3 and run the DSP at 144 MHz. We also use the PLL to divide the 144 MHz by 3 and attach that signal to ECLKOUT.
The spec’s on page 71 seem to imply that is ECLKOUT is based on a 48 MHz ECLKIN, then the period jitter per spec of +/- 0.9 nanoseconds would result in +/- 4.3% jitter. Is that true for ECLKOUT based on ECLKIN?
Would the spec for ECLKOUT based on the PLL output have the same amount of jitter?"
