IIS to Coaxial Adapter Board (Upgraded RCA Socket) + USB Board High Quality Digital Interface USB for Amanero USB Module

IIS to Coaxial Adapter Board (Upgraded RCA Socket) + USB Board High Quality Digital Interface USB for Amanero USB Module

Features:
- UTX_B IIS adapter board is designed for Amanero USB module to make up for the regret that this interface has no coaxial output. The input interface of IIS is 20P busbar, and for Amanero USB module can be directly installed on the interface. Meanwhile, in order to meet the different usage scenarios of buyers, the design adds more IIS inputs.
- In addition to the 4-wire IIS signal with MCLK output for Amanero USB, this board can also be connected to 3-wire IIS output without MCLK output, such as Bluetooth module, for Raspberry Pi, etc. Different from the common WM8804/WM8805IIS coaxial solution, this board adopts more advanced and more professional grade SPDIF digital synthesis solution, support high specification up to PCM384KHz/32Bit coaxial output, signal source synchronization clock, avoid the use of PLL clock generation resulting in cold and thin sound, with high analytical power, speed sense and transparent sense, three frequency balance, and stronger analog sound.
- Size: 80mm x 80mm

Input:
- 2-Channel IIS input:
  2 x 10P female, compatible with USB interface for Amanero
  1 x 5P, used for Bluetooth module, such as Raspberry Pi and so on.
- 3-Wire mode (without the need of MCLK input
- 4-Wire mode (MCLK input frequency: 22.5792MHz/24.576MHz)

Output:
- Coaxial: PCM 44.1KHz ~ 384KHz/32Bit
- Optical: PCM 44.1KHz ~ 192KHz/32Bit
- When the output is set to 32Bit, some decoders may not be able to lock if they do not support it, simply set it back to 24Bit output.

Power Supply:
- Working voltage: DC stabilized voltage +3.3V, ±5%
- Working current: <60mA
- External power supply current: >100mA

The board can be powered in two ways as follows:
- Obtain power from the 20P female port of the USB module, which must be connected the J6 jumper.
- Power from the DC_IN input interface of the board, the J6 jumper must be disconnected.

Note:
- J6 jumper shipment is connected by default, you need to use electric soldering iron operation for disconnecting.
- Only one power supply mode can be used at one time. Otherwise, the USB module and power supply will be damaged.
- The pins of the USB module should be installed on the side of the USB socket. If the pins are installed on the bottom of the USB module, they will not be usable.

Package Included:
- 1 x IIS to Coaxial Board
- 1 x USB Board (Domestic Italian USB Board)
