Detailed Description
Table 2-121. JC_REFCLK_FB_DIV_CONTROL (continued)
Controls the feedback divider value
See
Figure
1-3, and Appendix A for provisioning details.
Note: JC_CHARGE_PUMP_ CONTROL (4/5.37126) needs to be set
accordingly based on FB_DIV range. Refer
Control Setting (CP_CTRL)
Table 2-122. JC_RXB_OUTPUT_CLK_DIV_CONTROL
Receive Byte Clock Output Divider Value. This divider value is always
provisioned with the same value as RXTX_DIV[6:0]. See
Appendix A for provisioning details. This value is only used when the jitter
cleaner is used to source the receive parallel interface output clock. Legal
programmed values are greater than or equal to 6
1 = Enables output divider (RXTX_DIV)
0 = Disables output divider
RX/TX SERDES Output Divider Value
See
Figure
1-3, and Appendix A for provisioning details Legal
programmed values are greater than or equal to 6

Charge pump buffer control
Charge pump control. When JC PLL is used, CP_CTRL[13:0] values
need to be set according to FB_DIV[6:0] range. Refer
