![]() ![]() In a serial clock distribution inputs are fed by the output of the former device in the chain. Also with a high number of T-connectors in a chain, the reliability of the entire system is at risk. Often the input impedance is not known and level problems can occur. All devices must use high-impedance inputs and the last point in the chain must be terminated. Each BNC T-connector is feeding the signal to one word clock input and to the next device. digital audio equipment with either BNC word-clock or coaxial S/PDIF inputs. #Coaxial word clock spliter generator#In a parallel clock distribution multiple devices are connected to the same word clock output using BNC T-connectors in a chain as for elder Ethernet networks. A word-clock generator will centralize all of the timing of various pieces. If no internally termination is possible, an external 75 Ohm BNC terminator via BNC-T connector shall be installed. Word clock inputs for the star configuration should always be 75 Ohms terminated. The star configuration is the preferred method to connect several devices to the word clock master. For each device an individual word clock output is needed (distribution amplifier). Because no published standards for word clock exist, the compatibility between different devices is not guaranteed.Įvery device is connected in a star configuration. If distributed via AES-3, 110 Ohm twisted pair cables are used. ![]() Word Clock is distributed with 75 Ohm coax cables. Horizontal slope resulting from capacitive or transformer coupling Down: real-world signal with slower rise and fall times and the ![]()
