The Selection and Configuration of Synchronization Clock for HDLC Protocol
Synchronous HDLC serial communication, different from ordinary asynchronous communication, the clock signal plays an important role, only the sender and receiver use the same clock, can achieve highly reliable data transmission.
Design and Implementation of HDLC Synchronous Serial Port for ATC Radar
The ATC radar data network uses the HDLC protocol to transmit target data, and the ATC radar and ADS-B equipment must be able to support the HDLC protocol and provide multiple synchronized serial ports for outputting radar data.
