pls check my triangular-wave generator designed by guide of TI'S DOC, the jitter of output wave is large,how to deal with it

my design follow the guidance of TI'S DOC:ZHCU066-June 2013 by John Caldwell,using TI 's comps OPA2365 and tlv3502;

on my board, the jitter of tri-wave is so bad ,as a result,the backward PWM wave is not qualified.

any guys here pls give me some advise,many tks.
