Figure 18 - Clock Redundancy with Two Independent Timing Cards
The following is an example of how active/redundant setup can be configured.
The active timing card is set based on the desired application and is set to:
Primary master mode, SEC_MSTR=0
Normal Mode, MODE_SEL1:0=00 (forces device to the input reference set at REF_SEL)
Automatic mode, MODE_SEL1:0=11 (allows device to auto-switch if reference fails)
The HOLDOVER and REF_FAIL pins help evaluate quality of clocks and quality of redundant clock.
The redundant timing card is set based on desired applications and is set to:
Normal (manual) mode, MODE_SEL1:0=00
REF2 and REF2_SYNC as the input reference, REF_SEL1=1 (forces redundant device to lock to output
of active card)
Secondary master mode, SEC_MSTR=1
The HOLDOVER and REF_FAIL pins help evaluate quality of clocks and quality of redundant clock.
