Word clock is a synchronization signal used by compatible professional digital audio equipment to keep devices operating from a common timing reference. Equipment such as digital consoles, audio interfaces, converters, recorders and clock generators may use BNC connections for word clock input and output.
A properly matched 75-ohm BNC cable provides the coaxial connection between compatible word clock devices. AV-Cables Word Clock assemblies are designed specifically for professional 75Ω applications.

Why Use a 75 Ohm Cable for Word Clock?
Many professional word clock connections are designed around a 75-ohm coaxial signal path. Using cable and connectors that match the specified impedance helps maintain the intended electrical characteristics of the connection.
Check Your Equipment Always confirm the word clock connection and termination requirements specified by the equipment manufacturer before connecting devices.
Word Clock BNC vs. 50 Ohm RF BNC
BNC describes the connector style, not the impedance of the cable. AV-Cables manufactures both 75-ohm and 50-ohm BNC assemblies for different professional applications.
| Cable Type | Impedance | Typical Application |
|---|---|---|
| Word Clock BNC | 75Ω | Digital audio synchronization |
| RF BNC | Commonly 50Ω | RF, wireless, communications and test equipment |

Word Clock Cable Frequently Asked Questions
What impedance should a word clock cable be?
Many professional word clock systems use 75-ohm coaxial connections. Check the specifications for your equipment to confirm its required impedance and termination.
Is a word clock cable the same as a standard BNC cable?
BNC identifies the connector style. BNC cables can be manufactured for different impedances and applications. For equipment specifying 75-ohm word clock connections, use a properly matched 75-ohm coaxial assembly.
What equipment uses word clock?
Compatible digital audio interfaces, converters, mixing consoles, recorders, master clock generators and other professional digital audio equipment may provide BNC word clock inputs or outputs.
Can I order different Word Clock cable lengths?
Yes. Select the required length and available options on the Word Clock cable product page. AV-Cables can also manufacture custom assemblies for specialized installations.
Can I use a 50-ohm BNC cable for word clock?
Use the impedance specified by the equipment manufacturer. When the equipment specifies a 75-ohm word clock connection, use a properly matched 75-ohm cable rather than substituting a 50-ohm RF assembly.
