ES9018K2M Decoder Board High Configuration Version I2S Input High Fidelity Raspberry Pi Digital Audio Play

ES9018K2M Decoder Board High Configuration Version I2S Input High Fidelity Raspberry Pi Digital Audio Play

Features:
- It adopted the original ES9018K2M, and the original JRC4580D is used for operational amplifier.
- High precision active crystal oscillator is adopted, solid state capacitor is used for main filter, and ruby electrolytic capacitor is used for positive and negative voltage.
- The high precision chip resistor is selected to ensure a good signal-to-noise ratio of the whole machine.
- I2S input adopts XH2.54 6P base, coaxial input welding.

Advantages:
- Used in conjunction with the interface, there is no defect in PCM DSD switching.
- DC power supply 5V0.5A, easy to use.
- ES9018K2M parameters are relatively complete.
- The board size is 53 x 48MM, and the small size is easy to install.
- The MCLK of ES9018K2M is an independent clock and can use 50Mhz-100Mhz, so only input DATA BCK LRCK is enough and very convenient.

FAQ:
Q: Why does I2S have 6 wires? Isn't it normal that there are 4 wires?
A: ES9018K2M integrates MCLK, but it is designed to facilitate upgrading to a better MCLK master clock. You can upgrade the OCXO or femtosecond clock independently. The crystal oscillator on the board must be removed when upgrading the clock.

Q: Which development board can it support?
A: Support Raspberry Pi 2B+ 3B 3B+ 4B, for ASUS tinker board S, for Songguo ROCK 64 development boards.

Parameter:
- Input power: DC 5V 0.5A
- Size: 53 x 48mm
- Installation hole size: 43 x 38mm
- Distance between 2 RCA output base:  20mm
- Input support: I2S/DSD: 32bit 384k/DSD64, DSD128, DSD256
- Signal input explanation:
  Coaxial version: I2S seat is reserved, but I2S input channel is closed; input I2S signal input is invalid, and only coaxial signal can be input.
  I2S version: No coaxial signal input function, coaxial signal input is invalid, only I2S signal can be input.
- I2S pin Description: I2S and coaxial input can only choose one of the two, and cannot be input at the same time, otherwise the sound conflicts.

Package Included:
- 1 x Board
- 1 x 6pin Cable
