 Last test is CL(C261,C272) is 18pF and change those value to 12pF then
 retest as result below :

 System OFF 4/13 17:30:40 ~ 4/16 17:33:10. lead standard time 3 Sec
 Caculate value is +202.9167.(Meet spec.)

 Main Source TXC are pass, we'll discuss criteria for 2nd source
 (+/-20ppm).
 I think you can close this issue.
