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
