CSENT-TX CSENT Transmitter
The CSENT-TX core implements a transmitter for the Single Edge Nibble Transmission (SENT) protocol. It complies with the SAE J2716 standard and supports both synchronous and asynchronous transmissions.
In asynchronous mode, the core autonomously initiates transmission, as data become available in its input-data register. Under synchronous mode, transmission is triggered by either the host system via the core’s control registers, or when the core receives a valid master trigger pulse via the SENT interface.
The core reports its status using two signals, one indicating that a transmission is in progress, and a second one reporting the completion of a frame's transmission. The CSENT-TX also provides access to its registers via a 32-bit APB, or an AXI4-Lite or a generic interface. The core contains no latches or tri-states, is fully synchronous with a single clock domain, and includes no multicycle or false paths.
The CSENT-TX core has been rigorously verified and is production proven.
