TX Disable Pin Sample Clauses
The TX Disable Pin clause defines the function and use of a specific hardware pin on a device, typically used to control the transmission state of a transceiver or similar component. In practice, this pin allows users to electronically disable the transmitter output by applying a certain voltage or signal, which can be useful during maintenance, testing, or to prevent unwanted signal transmission. The core purpose of this clause is to provide a clear method for safely and efficiently controlling the operational state of the transmitter, thereby enhancing device safety and operational flexibility.
TX Disable Pin. TX Disable Pin (TX_DIS) is an input pin from the Host, operating with active-high logic. This pin is pulled up in the CFP8. When TX_DIS is asserted, all of the optical outputs inside a CFP8 module shall be turned off. When this pin is de-asserted, transmitters in a CFP8 module shall be turned on according to a predefined TX turn-on process which is defined by the state diagram shown in the ³CFP MSA Management Interface Specification´. A maximum time is defined for the transmitter turn-on process. This time is vendor and/or technology specific and the value is stored in a MDIO register. This pin can be optionally configured as Programmable Control 1 Pin after Reset. One MDIO register which defines if the module supports this optional configuration or not, is prepared in the NVR region. Please refer to Ref. [4] for more details.
