Shunyata Research Sigma-X Clock-50 | 50-Ohm BNC Clock Cable
Shunyata Research Sigma-X Clock-50 is a reference 50-ohm coaxial clock cable for components that specify a 50-ohm BNC clock interface. It uses SPC conductors with a 100% braided SPC shield, PTFE dielectric, PMZ construction, 35 TAPc elements, dual-element CMode filtering and four days of KPIP v2 processing.
Choose Clock-50 only when both the clock output and input are specified for 50 ohms. For 75-ohm clock connections, see Sigma-X Clock-75. See all our Shunyata Research cables and power products.

SIGMA-X CLOCK-50
Shunyata Research Sigma-X Clock-50 is a reference 50-ohm coaxial clock cable with SPC conductors, an SPC 100% braided shield, PTFE dielectric, BNC connectors, 35 TAPc elements, dual-element CMode filtering, PMZ construction and four days of KPIP v2 processing.
WHO IS SIGMA-X CLOCK-50 FOR?
Digital clock systems whose BNC clock input and output are specified for 50-ohm operation.
CLOCK-50 VS. CLOCK-75
The difference is interface impedance. Use Clock-50 for 50-ohm equipment and Sigma-X Clock-75 for 75-ohm equipment. Shunyata matches each cable to a connector of the same impedance.
TECHNOLOGY
 | TAPc (Transverse Axial Polarizer) is Shunyata Research's patent-pending technology that couples to the electromagnetic fields around signal conductors. It works like a polarizer, passively reducing electromagnetic distortion. Sigma-X Clock-50 uses 35 TAPc elements. |
 | CMode is Shunyata Research's filter for common-mode noise, which is harder to measure and remove than differential noise. Shunyata designed it to reduce that noise without the compression effects of conventional filters. Sigma-X Clock-50 uses a dual-element CMode filter. |
 | PMZ (Precision Matched Z) is Shunyata Research's ultra-precise production standard. The extrusion and braiding machines run at a quarter of normal speed, so the conductor surface, dielectric extrusion and braided shield are held to very tight tolerances. |
 | KPIP v2™ is Shunyata Research's proprietary Kinetic Phase Inversion Process, applied to the conductor and terminal metals. Sigma-X Clock-50 receives four days of KPIP v2 processing, which Shunyata says greatly reduces burn-in time. |
