On our board,we use two LMK03806s.
When two LMK03806s internal VCO is configured to 2578M, the output clock 322M has high TIE jitter which is about 1.3ns.see attached file "LMK0-322(VCO 2578)_LMK1-156(VCO 2578)"
When one LMK03806 internal VCO is configured to 2578M and another LMK03806 internal VCO is configured to 2500M , the LMK03806 that internal VCO is configured to 2578M outputs 322M low TIE jitter which is about 18ps.see attached file "。"LMK0-322(VCO 2578M)_LMK1-156(VCO 2500) "
Two LMK03806s use different power source. there are 5000mil between the two LMK03806. Our schematic is at attachment "LMK03806BISQE".
Please analyse this problem.
