PLL1_HOLDOVER_EN |
RW |
1 |
Enable PLL1 Holdover function. When PLL1_HOLDOVER_EN is 1 the holdover circuit is enabled. When PLL1_HOLDOVER_EN is 0 the holdover circuit is disabled. |
[6] |
PLL1_STARTUP_HOLDOVER_EN |
RW |
1 |
When PLL1_HOLDOVER_FORCE is 1, PLL1 enters holdover mode immediately on start-up. |
[5] |
PLL1_HOLDOVER_FORCE |
RW |
0 |
PLL1 Force Holdover Operation. When PLL1_HOLDOVER_FORCE is 1 PLL1 enters holdover mode regardless of other conditions. |
[4] |
PLL1_HOLDOVER_RAIL_MODE |
RW |
0 |
PLL1 Rail Detection Level Relative or absolute.
PLL1_HOLDOVER_RAIL_MODE– Level Mode
0– Absolute-Level
1– Relative to Level set at Lock |
[3] |
PLL1_HOLDOVER_MAX_CNT_EN |
RW |
1 |
PLL1 Holdover Max Counter enable. Wait for PLL1_HOLDOVER_MAXCNT cycles before starting Auto-CLKin-Switch procedure. |
[2] |
PLL1_HOLDOVER_LOS_MASK |
RW |
0 |
PLL1 Holdover LOS Mask. When PLL1_HOLDOVER_LOS_MASK is 1 then Loss of Source has no effect in the activation of holdover. |
[1] |
PLL1_HOLDOVER_LCKDET_MASK |
RW |
1 |
PLL1 Holdover Lock Detect Mask. When PLL1_HOLDOVER_LCKDET_MASK is 1 then Lock Detect has no effect in the activation of holdover. |
[0] |
PLL1_HOLDOVER_RAILDET_EN |
RW |
0 |
PLL1 Holdover Rail Detection Enable. When PLL1_HOLDOVER_RAILDET_EN is 1 the rail detection circuit is enabled. When PLL1_HOLDOVER_RAILDET EN is 0 the rail detection circuit is disabled. |
