VCOCXO Sync-Clock 1025

from €595,00 exclusive of VAT

Ultra-Low Noise 10MHz-to-25MHz Audiophile Clock Converter

The Sync-Clock 1025 is a high-end board that analogously converts a 10MHz master clock signal—such as from a Mutec REF10—into a pristine, phase-locked 25MHz signal. Engineered specifically to eliminate the phase noise, broadband jitter, and digital harshness caused by standard network switch processors, it provides a transformative high-resolution upgrade to your digital audio streaming ecosystem. By ensuring perfect synchronization, the Sync-Clock 1025 delivers an analog-like soundstage with a significantly lower noise floor and improved holographic imaging.

Description

The Missing Link Between Your Master Clock and Network Switches

  • 10MHz input from masterclock , 25MHz synchronized output

  • Perfect Impedance Matching (Available in 50 Ω or 75 Ω)
  • State-of-the-Art SC-Cut VCOCXO
    At the heart of the circuit lies an ultra-premium, oven-controlled VCOCXO utilizing an advanced SC-Cut (Stress Compensated) crystal architecture. This oscillator is entirely immune to thermal drifts and microphonics (vibrations caused by sound waves in your listening room). This results in a staggering phase noise floor of -135 dBc/Hz at a 100 Hz offset.
  • Zero Jitter-Stacking (Pure Analog PLL)
    Unlike mainstream clock multipliers that rely on digital, fractional synthesis, the Sync-Clock 1025 features a fully discrete, pure analog Phase-Locked Loop (PLL) built around the renowned architecture. With zero digital interpolation, the clock signal remains entirely in the analog domain, preserving the flawless timing of your master clock.
  • Ultra-Slow 2Hz Analog Loop Filter
    The bespoke, passive 3rd-order loop filter is engineered with an exceptionally low cutoff frequency of just 2Hz. This allows the oscillator to track the master clock with absolute relaxation. High-frequency switching noise and fasedetector ripple are ruthlessly stripped away using ultra-premium film capacitors before the clock signal ever reaches your switch chip.
  • Fully Galvanically Isolated Input
    To prevent high-frequency digital noise from the network switch from leaking back into your sensitive master clock (and to eliminate ground loops entirely), the BNC input features a studio-grade RF pulse transformer. The grounding systems are 100% physically isolated.
  • Unrivaled Power Supply Hygiene (< 0.8 µV RMS)
    A clock is only as clean as the power feeding it. The Sync-Clock 1025 utilizes two independent ultra-low-noise linear Voltage regulators. Delivering a class-leading noise floor of under 0.8 microvolts, it provides the purest voltage technically achievable.
