D1b USB Digital Interface Ultimate version Femtosecond Crystal Oscillator Replacement For Amanero
What is a digital interface?
It is a digital audio interface, commonly used to connect computers, tablets, players, etc., to convert the USB port to an IIS interface for audio data transmission. The index level is higher than that of a computer's own sound card, and the output I2S signal is more convenient to connect to various DAC decoders.
Why choose this USB interface?
It uses the design for ARM+CPLD, and everyone generally believes that its sound quality is better than that for XMOS, with a more musical sense and a stronger taste. This interface can be upgraded with femtosecond crystal oscillator for better sound.

Features:
- The sound is loose and balanced, delicate and round
- Compatible with Italian digital interface
- Component process: Military-level A-level PCB, double-sided immersion gold process. High-precision placement machine, fully automatic welding components. Official original circuit structure, enthusiast-level SMD resistors and capacitors. Supports flashing any firmware version specified by the original manufacturer and original driver. For ARM version 3U2C, CPLD version XC2C64A consistent with the official
- Independent power supply: add GND, DP, DM, 5V for external independent power supply under the USB socket
- CPLD soft control: adopt for ARM+CPLD architecture, USB-2.0 high-speed transmission 480Mb/S asynchronous USB to IIS professional audio architecture. For ARM V7M is responsible for the coordinated processing of USB data, and CPLD alone completes clock processing, sampling reconstruction and IIS data processing. With reasonable and efficient audio quality, music structure and processing methods, it will surprise you when listening to music using the USB interface
- Driver-free: Supports for Apple mobile phones, Linux, Raspberry Pi and Apple MAC. Android 4.4 and above systems with OTG are all driver-free. For Windows, it needs driver
- Low noise crystal oscillator: It can be upgraded with American femtosecond crystal oscillator with better performance. The crystal oscillator pin is compatible with CCHD-575. Femtosecond level refers to the short-term stability of the crystal oscillator, and the phase noise is usually expressed by the jitter value. The general crystal jitter parameters are expressed in ps, but when the jitter value is less than 1PS, femtosecond (fs) is used. At present, only a few particularly excellent crystal oscillators can achieve femtosecond jitter performance
- Femtosecond crystal oscillator's frequencies are 24.576M and 22.5792M
- Signal output: Generally, the output is only connected to the 4 wires of the I2S interface, plus 1 ground wire. They are: MCLK, FSCLK, BCLK, DATA, and GND. FSCLK corresponds to the LRCK or WCLK of the decoder board (including unsoldered DuPont headers)
- I2S output: For Inter IC Sound bus integrated circuit built-in audio bus. It adopts the design of transmitting clock and data signals along separate wires. By separating the data and clock signals, the distortion induced by time difference is avoided
- Use scenario: computer USB connection decoder. Let your decoder without USB connect to your computer to play music. Old-style decoders can also be connected to a computer, with richer digital music resources (coaxial and balanced adapter boards are optional). Add USB input for decoder
- USB to I2S makes it widely used
Parameters:
