CDCI6214: CDCI6214 configuration output waveforms amplitude on Y1 to Y4 output pins is not correct

Part Number: CDCI6214
Other Parts Discussed in Thread: , TICSPRO-SW


Input Ref on XIN:   

1) crystal , on CDCI6214EVM 

2) LVCOMS (VDDCO=VDDREF= +3.3V),  on prototype board

Output clock configuration requirements: 

Y0: 25MHz, 

Y1:  LVDS, 100MHz, +1.8V

Y2:  LVCMOS, P+N+, 100MHz, +1.8V

Y3:  LVCMOS, P+N+, 125MHz, +1.8V

Y1:  LVDS, 100MHz, +1.8V

TICS Pro version: v1.7.5.7

I tried the related configurations below: 

chX_1p8vdet --1  (1.8V)

Address 3Bh, (bit 12-11) chx_lvds_cmtrim_inc = 2
Address 3Bh, (bit 4) chx_lvcmos_drv --1 (Fast)
Address 3Bh, (bit 2, bit1) CH0_LVCMOS_DRV=fast mode(3h)=normal mode(28ohm)

Address 1Bh,
bit 14: ip_byp_en_ch3 = 1
bit 13: ip_byp_en_ch3 = 1
bit 12: ip_byp_en_ch2 = 1
bit 11: ip_byp_en_ch1 = 1

The Register Commit flow was used by me. 

Unfortunately, except for correct output 25MHz waveform on Y0 pin is correct (both amplitude and frequency) ,   I still can't get the desired correct clock  waveforms on output Y1 to Y4 pins.  After AC-couple was set on my Oscilloscope to measure these output waveforms ,  the related output frequencies look right (meet the desired setting values) .  The output LVCMOS clocks' amplitude  are not right and the output clock wings of LVDS are not right.  

Maybe I missed some critical configuration in somewhere. Would you help check it and give me the correct configuration values?
