Description
Number of clock cycles (minus 1) of the Divider 0 input during which the Divider 0 output
stays low. A value of 0x7 means the divider is low for eight input clock cycles (default: 0x0).
Number of clock cycles (minus 1) of the Divider 0 input during which the Divider 0 output
stays high. A value of 0x7 means the divider is low for eight input clock cycles (default: 0x0).
Bypass and power-down the divider; route input to divider output.
[7] = 0; use divider.
[7] = 1; bypass divider (default).
Nosync.
[6] = 0; obey chip-level SYNC signal (default).
[6] = 1; ignore chip-level SYNC signal.
Force divider output to high. This requires that nosync also be set.
[5] = 0; divider output forced to low (default).
[5] = 1; divider output forced to high.
Selects clock output to start high or start low.
[4] = 0; start low (default).
[4] = 1; start high.
Phase offset (default: 0x0).
Connect OUT0 and OUT1 to Divider 0 or directly to CLK input.
[1] = 0: OUT0 and OUT1 are connected to Divider 0 (default).
[1] = 1;
If 0x1E1[0] = 0, the CLK is routed directly to OUT0 and OUT1.
If 0x1E1[0] = 1, there is no effect.
Duty-cycle correction function.
[0] = 0; enable duty-cycle correction (default).
[0] = 1; disable duty-cycle correction.
Number of clock cycles (minus 1) of the Divider 1 input during which the Divider 1 output stays
low. A value of 0x7 means the divider is low for eight input clock cycles (default: 0xB).
Number of clock cycles (minus 1) of the Divider 1 input during which the Divider 1 output stays
high. A value of 0x7 means the divider is low for eight input clock cycles (default: 0xB).
Bypass and power-down the divider; route input to divider output.
[7] = 0; use divider (default).
[7] = 1; bypass divider.
Nosync.
[6] = 0; obey chip-level SYNC signal (default).
[6] = 1; ignore chip-level SYNC signal.
Description
Set output current level in LVDS mode. This has no effect in CMOS mode.
