Amanero Italian interface is an excellent USB interface
A large number of Italian interfaces on the market use the official solution, but only the i2s signal output and no spdif output
Many businesses use w8805 and other i2s conversion spdif chips for data conversion. However, the change of data brought by this conversion is not guaranteed, and the sound brought by each conversion chip will also be different
In order to make better use of the sound of the Italian USB solution, this USB interface was produced. Cpld directly completed all original Italian i2s signal processing and spdif signal conversion
The interface performance solution continues to take advantage of all the performance of Italy. New advantages: coaxial can output all sampling formats under 384k, coaxial dsd dop128 fiber coaxial dop64 which cannot be completed by all interfaces on the market. With the es9028 es9038 dac chip shipping coaxial optical input Both can support dsd dop.
The USB interface sampling is indicated by the colorful LED:
Yellow: 44.1k
Green: 48k
Green: 88.2k
Purple: 96k
Red: 176k
Blue: 192k
Orange: 352k
White: 384k
Yellow: dsd64
Green: dsd128
Green: dsd256
Purple: dsd512
Features:
1: The board uses FPGA to complete spdif conversion output and dsd dop output
2: FPGA completes i2s data differential and ordinary i2s output
3: The internal and external power supply is switched through the switch, and the external power supply is recommended to use 6-9v
4: External power supply uses ultra-low dropout low ripple voltage stabilized ic
5: Use multi-phase separate power supply, each crystal oscillator, FPGA, master control, powered by a separate voltage stabilized ic to reduce interference between power supplies
6: Coaxial use mkp1837 copper pin coupling capacitor and da101 coupling transformer, as audio enthusiasts should not be unfamiliar
7: Seven-color sampling indication, it is better to watch the current sampling frequency directly
8: This shop provides three versions of crystal oscillator: ordinary version, gold-plated shell 0.1ppm, femtosecond version.
9: Use 45.1584M and 49.152M frequency crystal oscillator
10: The coaxial optical fiber signal is output separately by the FPGA port, the coaxial can output 384k dsd dop 128 and the optical fiber can output 192k dsd dop64
