Reg.
Addr.
(Hex) Bits Name Description
0x19C 5 Bypass Divider 3.2 Bypasses (and powers down) 3.2 divider logic, routes clock to 3.2 output.
0: does not bypass (default).
1: bypasses.
4

Bypasses (and powers down) 3.1 divider logic, routes clock to 3.1 output.
0: does not bypass 3.1 divider logic (default).
1: bypasses 3.1 divider logic.
3 Divider 3 nosync Nosync.
0: obeys chip-level SYNC signal (default).
1: ignores chip-level SYNC signal.
2
Divider 3 force high
Force Divider 3 output high. Requires that nosync also be set.
0: forces low (default).
1: forces high.
1 Start High Divider 3.2 Divider 3.2 starts high/low.
0: starts low (default).
1: starts high.
0 Start High Divider 3.1 Divider 3.1 starts high/low.
0: starts low (default).
1: starts high.
0x19D 0 Divider 3 DCCOFF Duty-cycle correction function.
0: enables duty-cycle correction (default).
1: disables duty-cycle correction.
0x19E [7:4] Low Cycles Divider 4.1 Number of clock cycles (minus 1) of 4.1 divider input during which 4.1 output stays low.
A value of 0x0 means that the divider is low for one input clock cycle (default = 0x0).
[3:0]
High Cycles Divider 4.1
Number of clock cycles (minus 1) of 4.1 divider input during which 4.1 output stays high.
A value of 0x0 means that the divider is high for one input clock cycle (default = 0x0).
0x19F [7:4] Phase Offset Divider 4.2 Refer to LVDS/CMOS channel divider function description (default = 0x0).
[3:0] Phase Offset Divider 4.1 Refer to LVDS/CMOS channel divider function description (default = 0x0).
0x1A0 [7:4] Low Cycles Divider 4.2 Number of clock cycles (minus 1) of 4.2 divider input during which 4.2 output stays low.
A value of 0x0 means that the divider is low for one input clock cycle (default = 0x0).
[3:0] High Cycles Divider 4.2 Number of clock cycles (minus 1) of 4.2 divider input during which 4.2 output stays high.
A value of 0x0 means that the divider is high for one input clock cycle (default = 0x0).
0x1A1 5 Bypass Divider 4.2 Bypasses (and powers down) 4.2 divider logic; route clock to 4.2 output.
0: does not bypass 4.2 divider logic (default).
1: bypasses 4.2 divider logic.
4 Bypass Divider 4.1 Bypasses (and powers down) 4.1 divider logic; route clock to 4.1 output.
0: does not bypass 4.1 divider logic (default).
1: bypasses 4.1 divider logic.
3
