Description
0x194
4
Divider 1 start high
Selects clock output to start high or start low.
0: starts low (default).
1: starts high.
[3:0]
Divider 1 phase offset
Phase offset (default = 0x0).
0x195
1
Divider 1 direct to output
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.
0
Divider 1 DCCOFF
Duty-cycle correction function.
0: enables duty-cycle correction (default).
1: disables duty-cycle correction.
0x196
[7:4]
Divider 2 low cycles
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).
[3:0]
Divider 2 high cycles
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).
0x197
7
Divider 2 bypass
Bypasses and powers down the divider; routes input to divider output.
0: uses divider.
1: bypasses divider (default).
6
Divider 2 nosync
Nosync.
0: obeys chip-level SYNC signal (default).
1: ignores chip-level SYNC signal.
5
Divider 2 force high
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.
4
Divider 2 start high
Selects clock output to start high or start low.
0: starts low (default).
1: starts high.
[3:0]
Divider 2 phase offset
Phase offset (default = 0x0).
0x198
1
Divider 2 direct to output
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.
0
Divider 2 DCCOFF
Duty-cycle correction function.
0: enables duty-cycle correction (default).
1: disables duty-cycle correction.
