Best Pll Digital Frequency Synthesis

Yamaha Montage8 88-key Synthesizer Workstation, Black

The Motion Control Synthesis Engine unifies and controls two iconic Sound Engines: AWM2 (high-quality waveform and synthesis) and FM-X (modern, pure Frequency Modulation synthesis.).
Motion Sequences are tempo-synchronized, completely customizable control sequences that can be assigned to virtually any synthesizer parameter and provide incredible new ways of creating sound..
Montage features professional, stereo balanced outputs with “Pure Analog Circuit” digital to analog conversion..
Eight rotary encoders and faders with step ladder LED. Note Capacity: Approx. 130,000 notes.
From high definition reverbs to incredibly detailed Virtual Circuit Modeling (VCM) effects, Montage is loaded.

1 amp USB charging port offers an easy way to charge smartphone or other portable electronics.

Using quartz crystal for frequency stabilization, and receiving frequency will not drift when temperature changes.
Using professional audio DSP to process and analyze audio signal, auto mute when there is no signal or week signal as big FM base noise, in order to get rid of the annoying rustle of traditional FM radio.
Advanced digital audio signal processing (DSP) and FM phase-locked loop modulation technique (PLL) ensure less sound distortion and more stable performance.
Using incremental digital 360° rotating encoder to adjust volume and frequency, which is accurate, stable, durable, and also offers comfortable hand feeling.
LCD display is more intuitive and accurate, and has very low power consumption and tiny noise interference.

PLL (Phase Locked Loop) Technology: The X1s GT uses a high-performance PLL chip of ADI. The jitter is very low. It took half a year to finish the whole program design. The PLL core outputs low-jitter clock signals according to the music currently being played simultaneously to XMOS and DAC. Therefore, the digital signals are better..
Clock synchronization and External clock input technology: The X1s GT supports 10M external clock input. And it achieves clock synchronization of the whole device. The clock signals from PLL are synchronized by XMOS and ES9038Q2M. The DAC is working in the synchronized mode. PLL works in all digital input modes: USB, coaxial, optical..
Complex Fully-discrete Headphone AMPs: The X1s GT’s amp board has 4 fully-discrete headphone amplifiers. 277 parts and components in total, among which, 96 are BJTs. It uses ±9v power supply. It’s a “huge” amp board compared to those of the same level DACs with amps. The hardware performance is outstanding..
Unique Filter Modes: Instead of using the ES9038 series’ default filter modes, we designed 4 filter modes for the X1s GT with our own algorithm. The X1s GT was designed to be a special product. It must have its characteristics and they show our understanding of music..
