Description
Number of clock cycles (minus 1) of 3.1 divider input during which 3.1 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 3.1 divider input during which 3.1 output stays high. A value of
0x0 means that the divider is high for one input clock cycle (default = 0x0).
Refer to LVDS/CMOS channel divider function description (default = 0x0).
Refer to LVDS/CMOS channel divider function description (default = 0x0).
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).
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).
Description
Selects clock output to start high or start low.
0: starts low (default).
1: starts high.
Phase offset (default = 0x0).
Connects OUT2 and OUT3 to Divider 1 or directly to VCO or CLK.
0: OUT2 and OUT3 are connected to Divider 1 (default).
1: If Register 0x1E1[1:0] = 10b, the VCO is routed directly to OUT2 and OUT3.
If Register 0x1E1[1:0] = 00b, the CLK is routed directly to OUT2 and OUT3.
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 (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).
Bypasses and powers down the divider; routes input to divider output.
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).
Connects OUT4 and OUT5 to Divider 2 or directly to VCO or CLK.
0: OUT4 and OUT5 are connected to Divider 2 (default).
1: If Register 0x1E1[1:0] = 10b, the VCO is routed directly to OUT4 and OUT5.
If Register 0x1E1[1:0] = 00b, the CLK is routed directly to OUT4 and OUT5.
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.
