The new ultra-high-precision master clock generator G-02, equipped with OCXO high-precision crystal oscillator, can output 22.5792MHz or 10MHz clock. G-02 uses an independent clock output drive circuit, a new design of discrete high-speed transistors, and an advanced high-precision crystal clock source. Its heart is an ultra-high-precision OCXO with a constant temperature device, which controls the crystal oscillator and vibration circuit. Stable temperature, even if the temperature outside the machine reaches -20 to 70 degrees, the crystal oscillator inside the machine can still be kept at a constant temperature, allowing the machine to reach a very high± 0.01PPM frequency stability. With the exclusive circuit to reduce jitter, the sound quality is improved, the sound is more precise, and the musical expression is more powerful and charming. The power supply part adopts R-type transformer with large capacity, high efficiency and low magnetic leakage, filter capacitor of multi-capacity capacitor combination, low power consumption, high current, ultra-high-speed Schottky diode and other high-performance device applications, aiming to realize accurate clock Signal high-speed digital processing environment.
Clock processor
Every digital device needs a built-in clock circuit to generate the clock signal required for device operation. The main clock generator is a very stable oscillator that generates an external clock for the digital device (such as a turntable equipped with a clock input terminal). , D/A converter and SACD turntable, etc.). The main clock generator generates a higher-purity clock signal than the internal clock of the digital device, thus greatly improving the sound quality. By operating a device connected to a high-stability main clock, the time base error called Jitter is almost completely eliminated, greatly improving the image and the sense of space and the depth of the background.
Install the core of the ultra-high-precision OCXO component
The main clock generator adopts a high-precision crystal oscillator that is adjusted according to Esoteric''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s customized specifications and has a frequency accuracy of plus or minus 0.01 ppm (parts per milliom). G-02 is equipped with a built-in temperature-controlled crystal oscillator (OCXO), which can produce stable oscillations under different conditions. This is achieved by integrating the quartz crystal resonator and the oscillating circuit in a temperature control box, and maintaining a constant temperature of the internal crystal and important circuits. G-02 achieves a very high frequency stability of plus or minus 0.01 ppm under the condition of an external temperature ranging from -20 degrees Celsius to 70 degrees Celsius.
Newly designed clock output drive circuit composed of individual components
G-02 is equipped with a newly designed clock output drive circuit composed of individual components. This circuit uses a high-speed transistor to generate the best digital waveform that meets the requirements of ultra-high-speed and high-precision. Integrating with the heavyweight power supply circuit, this circuit composed of individual components provides a correct and stable clock signal to the audio equipment, leading to important improvements in sound quality.
Heavyweight power supply
This main clock generator is equipped with a heavyweight power supply circuit to fully support its high performance level. The selected large-scale R-Core transformer has the characteristics of low loss and low magnetic leakage. The rectifier circuit is composed of multiple filter capacitors and Schottky diodes that respond quickly to support high-speed digital processing, which helps to generate a high-precision clock. Signal. In terms of display circuits, each circuit block is equipped with an independent transformer and a dedicated power supply circuit to minimize the mutual interference between the blocks.
Support 10MHz clock and 22.5792MHz main clock output
G-02 can output support Esoteric''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s unique "Direct Master Clock Link" 10MHz clock and 22.5792MHz and 24.576MHz main clock signal output.
Three independent A/B/C output systems
In addition to outputting 1 times, 2 times, 4 times and 512 times (22.5792MHz/24.576MHz) of the existing basic frequency (44.1kHz or 48kHz), G-02 can also output 100kHz and 10MHz clock signals. Furthermore, in the frequency expansion mode (EXP), G-02 can output 8 times, 16 times, 32 times, 64 times, 128 times and 256 times the clock frequency, so that its clock signal can support a wide range of equipment. Including professional equipment. Each of these systems is equipped with two sets of output terminals, which can provide clock signals to up to six devices. Each of the six output terminals from A1 to C2 can individually set the output frequency; if only a single piece of equipment is connected, all output terminals except A1 can be turned off.
External 10MHz clock input terminal
G-02 is equipped with input terminals that can receive 10MHz external signals. This terminal can connect rubidium clock and GPS clock to further upgrade the system.
Feature 8, Esoteric special gold-plated BNC terminals
G-02 adopts factory-made BNC terminals that provide highly reliable contact. These durable and safe terminals can support heavy and thick High-End wires.
