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 digital components that specify a 50-ohm BNC clock interface. It uses SPC conductors with a 100% braided SPC shield, PTFE dielectric, BNC connectors, PMZ construction, TAPc, dual-element CMode filtering, and KPIP v2 processing.
Choose Clock-50 only when the connected clock input and output specify a 50-ohm interface; for 75-ohm clock connections, use Sigma-X Clock-75.

Who is Sigma-X Clock-50 best suited 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 Clock-75 for 75-ohm equipment.
Technology
Sigma-X Clock-50 combines Shunyata technologies for electromagnetic control, precision impedance, common-mode noise reduction, shielding, and conductor conditioning. Its model-specific 50-ohm BNC coaxial design uses SPC conductors, a 100% braided SPC shield, PTFE dielectric, PMZ, TAPc, dual-element CMode, and KPIP v2 processing.
TAPc
Patent-pending Transverse Axial Polarizer technology couples to electromagnetic fields surrounding signal conductors and is designed to reduce electromagnetic distortion. Sigma-X Clock-50 uses 35 TAPc elements.
PMZ
PMZ is Shunyata's precision production standard for tightly controlling conductor surfaces, dielectric extrusion, and braided-shield geometry to minimize impedance variance.
CMode
CMode is Shunyata's common-mode filtering technology, designed to reduce common-mode noise without the compression effects associated with conventional filtering. Sigma-X Clock-50 uses a dual-element CMode filter.
KPIP v2
Shunyata Research's proprietary Kinetic Phase Inversion Process is applied to conductor and terminal metals. Sigma-X Clock-50 receives four days of KPIP v2 processing.
50-Ohm BNC Clock Architecture
Sigma-X Clock-50 uses SPC conductors, a 100% braided SPC shield, PTFE dielectric, BNC connectors, and a specified 50-ohm characteristic impedance.
