About the 50 ohm : 75 ohm impedance converter
Model: CYB-ZC01 (50Ω male connector)
Model: CYB-ZC02 (75Ω male connector)
- Converts the impedance of the clock transmission path in audio systems from 50Ω to 75Ω.
- This product incorporates the L-network impedance matching circuit used in our Signature and Plus series master clocks. Unlike conventional resistive matching methods, it achieves highly precise impedance matching with extremely low loss and without degrading signal energy.
- The enclosure is constructed from carbon fiber composite material, which effectively suppresses minute vibrations transmitted through the cable. This contributes to improved stability and enhanced purity of the clock signal.
- This product is bidirectional and can be used in either direction, regardless of input or output.
- Please select the appropriate model according to the BNC connector configuration (male or female).
[ Product Features ]
Conventional impedance converters are generally designed as wideband devices, typically covering frequency ranges from approximately 0.1 MHz to 400 MHz.
However, such designs are not optimized for single-frequency applications like 10 MHz, and may introduce unnecessary loss and imperfect matching.
This product is specifically engineered for 10 MHz sine wave signals.
Each unit is individually tuned by carefully selecting and adjusting component values while being measured and verified using a network analyzer.
This dedicated tuning process ensures highly accurate impedance matching at the target frequency.
The male BNC connector used in the CYB-ZC02 is a 50Ω type; however, this does not affect performance.
[ Applications ]
- Improving the purity of 75Ω outputs from our conventional clock products
-
Example: Cybershaft Clock output (set to 50Ω) → [CYB-ZC01] → 75Ω outp
- Enhancing the connection quality between our clock products and Mutec MC-3+ USB
-
Example: Cybershaft clock output (set to 50Ω) → [CYB-ZC01] → 75 ohm BNC cable → MC-3+ USB
Our latest Signature and Plus series clock products already incorporate an L-network circuit for their 75Ω outputs, so this product is not required when using those models.
[ Specifications ]
Supported Impedance: 50Ω ↔ 75Ω
SWR: ≤ 1.10 Typ. 1.05 (at 10 MHz sine wave, 50Ω ↔ 75Ω)
Insertion Loss: 0.3%
[ Notes ]
Always use a BNC cable with the correct impedance when using this product.
This product is designed exclusively for our 10 MHz clock products. It is not suitable for other frequencies or square wave signals.
Each unit is individually measured, adjusted, and verified using a network analyzer.
