3.4.1.1.2. HSSI Serial Clock Sink
You can instantiate the HSSI Serial Clock Sink interface in the _hw.tcl file as:
add_interface <name> hssi_serial_clock end
You can connect the HSSI Serial Clock Sink interface to a single HSSI Serial Clock Source interface; you cannot connect it to multiple sources. This Interface has a single clk port role limited to a 1 bit width, and a clockRate parameter, which is the frequency of the clock driven by the HSSI Serial Clock Source interface.
An unconnected and unexported HSSI Serial Sink is invalid and generates error messages.
| Name | Direction | Width | Description |
|---|---|---|---|
| clk | Output | 1 | A single bit wide port role, which provides synchronization for internal logic |
| Name | Type | Default | Derived | Description |
|---|---|---|---|---|
| clockRate | long | 0 | No |
The frequency of the clock driven by the HSSI Serial Clock Source interface. When you specify a clockRate greater than 0, then this interface can be driven only at that rate. |
