The OSN3500 external clock signal input cable connector is faulty, and the external clock signal is degraded, causing the device cross board to frequently report BUS_ERR alarms. This problem can be solved by rebuilding the external clock signal input cable connector.
Parameter Meaning
"External source output mode" - used to set the output mode of the external source to 2M Bit/s or 2M Hz.
Impact on the system
Modifying the output mode of the external source may cause the clock source to be switched, and therefore may cause the service to generate errors.

Parameter Options |
Description |
|---|---|
|
2M Hz |
Configure the output mode of the external source to 2M Hz, and output a 2M Hz clock. |
|
2M Bit/s |
Configures the output mode of the external source to 2M Bit/s. |
Principle
The input mode of the two external clock signals can be freely set to 2MHz or 2Mbit/s, and the default input mode is 2Mbit/s; in practice, it should be ensured that the output mode matches the input mode of the receiver as much as possible.
Correlation with other parameters
