FunctionV-by-One HS
In THCV series, LOCKN signal shows the locked status of the CDR PLL implemented on the Receiver.
As defined in V-by-One® HS Standard, the signal indicates ”Low” when serial data is successfully received, CDR PLL is locked and the clock is recovered, while indicating “High” by using the external Pull-up resistor when CDR PLL cannot be locked during CDR training or due to the fault of received data.
