SMSL G1 Reference 10MHz OCXO Master Clock Generator

Overview

The SMSL G1 is a reference-grade 10MHz OCXO master clock generator designed to provide an ultra-stable clock source for high-end digital audio systems. Featuring a communication-grade SC-cut OCXO with ultra-low phase noise and factory-calibrated frequency accuracy below 3ppb, it delivers precise clock synchronization for compatible DACs, CD transports, and digital audio components.

Its dual constant-temperature design, supercapacitor-powered oscillator circuit, Noratel toroidal transformer, and multiple low-noise linear power supplies ensure exceptional long-term stability and low-jitter performance. Housed in a precision CNC-machined aluminum chassis, the G1 is an ideal reference clock solution for demanding Hi-Fi and professional audio applications.

Features

• Reference 10MHz OCXO Clock Source: Utilizes a communication-grade SC-cut 10MHz OCXO with ultra-low phase noise for highly accurate clock synchronization.

• Factory-Calibrated Accuracy: Every unit is factory calibrated to achieve frequency accuracy better than ±3ppb for long-term timing precision.

• Dual Constant-Temperature Design: Separately isolates and stabilizes the OCXO with a dual constant-temperature architecture for consistent clock performance.

• Four Independent Clock Outputs: Each output features an independent buffer circuit for stable multi-device synchronization and strong signal driving capability.

• Premium Linear Power Supply: Combines a Noratel toroidal transformer with multiple precision linear regulated power supplies to deliver exceptionally clean power.

• Supercapacitor Power Stabilization: Uses a supercapacitor-assisted power design to further improve oscillator stability and clock accuracy.

• Flexible Power Options: Supports both the built-in AC power supply and an external 9V–15V DC power supply for versatile installation.

• CNC Aluminum Chassis: Precision-machined all-aluminum enclosure with patented adaptive voltage switching technology, EMI-filtered AC input, and a 10-minute warm-up indicator for optimum performance.
