0: power on (default).
1: power off.
Number of clock cycles (minus 1) of the divider input during which divider output stays low.
A value of 0x0 means that the divider is low for one input clock cycle (default = 0x0).
Number of clock cycles (minus 1) of the divider input during which divider output stays high.
A value of 0x0 means that the divider is high for one input clock cycle (default = 0x0).
0: uses divider.
1: bypasses divider (default).
Nosync.
0: obeys chip-level SYNC signal (default).
1: ignores chip-level SYNC signal.
Forces divider output to high. This requires that nosync (Bit 6) also be set.
0: divider output forced to low (default).
1: divider output forced to high.
Selects clock output to start high or start low.
0: starts low (default).
1: starts high.
Phase offset (default = 0x0).
0: OUT0 and OUT1 are connected to Divider 0 (default).
1: If Register 0x1E1[1:0] = 10b, the VCO is routed directly to OUT0 and OUT1.
If Register 0x1E1[1:0] = 00b, the CLK is routed directly to OUT0 and OUT1.
If Register 0x1E1[1:0] = 01b, there is no effect.
Duty-cycle correction function.
0: enables duty-cycle correction (default).
1: disables duty-cycle correction.
Number of clock cycles of the divider input during which divider output stays low.
A value of 0x0 means that the divider is low for one input clock cycle (default = 0x0).
Number of clock cycles (minus 1) of the divider input during which divider output stays high.
A value of 0x0 means that the divider is high for one input clock cycle (default = 0x0).
0: uses divider (default).
1: bypasses divider.
Nosync.
0: obeys chip-level SYNC signal (default).
1: ignores chip-level SYNC signal.
Forces divider output to high. This requires that nosync (Bit 6) also be set.
0: divider output forced to low (default).
1: divider output forced to high.
Description
Sets output current level in LVDS mode. This has no effect in CMOS mode.
Power-down output (LVDS/CMOS).
Description
Bypasses and powers down the divider; routes input to divider output.
Connect OUT0 and OUT1 to Divider 0 or directly to VCO or CLK.
Bypasses and powers down the divider; routes input to divider output.
