Phase Offset Divider 3.2
Refer to LVDS/CMOS channel divider function description (default = 0x0).
[3:0]
Phase Offset Divider 3.1
Refer to LVDS/CMOS channel divider function description (default = 0x0).
0x1A0
[7:4]
Low Cycles Divider 3.2
Number of clock cycles (minus 1) of 3.2 divider input during which 3.2 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 3.2
Number of clock cycles (minus 1) of 3.2 divider input during which 3.2 output stays high.
A value of 0x0 means that the divider is high for one input clock cycle (default = 0x0).
0x1A1
5
Bypass Divider 3.2
Bypasses (and powers down) 3.2 divider logic; routes clock to 3.2 output.
0: does not bypass (default).
1: bypasses.
4
Bypass Divider 3.1
Bypasses (and powers down) 3.1 divider logic; routes clock to 3.1 output.
0: does not bypass (default).
1: bypasses.
3
Divider 3 nosync
Nosync.
0: obeys chip-level SYNC signal (default).
1: ignores chip-level SYNC signal.
2
Divider 3 force high
Forces 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 start high/low.
0: starts low (default).
1: starts high.
0
Start High Divider 3.1
Divider 3.1 start high/low.
0: starts low (default).
1: starts high.
0x1A2
0
Divider 3 DCCOFF
Duty-cycle correction function.
0: enables duty-cycle correction (default).
1: disables duty-cycle correction.
