The following is an upgraded version The Italian interface is added, the power supply is replaced with ON Semiconductor modules, and the FPGA upgrade program is the background GENG cleanup. The decoding supports up to 24-bit 384KHZ, which is not inferior to most popular decoding chips. The vocals are sweet, not illusory, and the real presence is fully present. The low frequency is powerful, soft and not fatty. High resolution, not noisy, relaxed and atmospheric. The more you listen, the more flavorful it is, and it is quite ear-catching. It is characterized by long-term listening and a good sense of music. In addition, the parameters have been tuned many times to make the sound more like a vinyl record, and the low frequency is sonorous and powerful. It has the function of automatic recognition of the external clock, which greatly improves the playability of this decoder board. This upgrade design uses dual FPGA clock asynchronous integration and noise reduction collaborative processing, with an external 10MHz clock input function, and an external clock input on the board. In addition to highly reducing the sound, it also reduces the design cost. Direct current output with external IV circuit, and lpf circuit, with precise noise cut-off technology to limit out-of-band noise, with extremely dark sound background, using nos method to access digital signals, and restore the sound with the original taste and integrity Resolutely abandon the external filter chip as required. Technical parameters of decoder board: Mono architecture composed of dual AD1865Rs, choose the internal operational amplifier of the chip.
I2S supports Philips I2S, xmos interface, Italian interface, etc., Bluetooth module with I2S output, only needs to connect to the three pins of BCK LRCK DATA. Voltage input : AC 12V-0 AC 0V-0 AC12V-1 AC 0V-1 AC9V-0 AC 0V-0 AC9V-1 AC 0V-1 AC9V-2 AC 0V-2 Each group of voltage cannot be connected in parallel (DIY players, please read carefully, and you will bear the consequences if you connect the wrong power supply and burn it) It is recommended to use dual transformers (ie, separate analog and digital circuits) Signal receiving plan: Dual FPGA Power module:Using LT1963 low noise voltage regulator module Signal support format: Coaxial supports pcm format, up to 24-bit 384Kkhz. External 10MHZ atomic clock, constant temperature clock, etc. Onboard high frequency dual crystal oscillator 2. Product name:Dual parallel R2R decoding AD1865R NOS DAC size:120*170mm signal input: 1.

For you have other metal sputtering needs, such as Al, Ag, welcome to contact us for discussion. Our regular used metal targets include:Cu, NiCr, NiCu, NiCuTi, C, Si, ITO targets. We can provide various metal sputtering OEM services by customer needs, such as sputtering graphite on aluminum, and sputtering copper on PI and PET. Copper-clad films by vacuum sputtering process have merits such as good uniformity of metal layer, productive, good adhesion, and high hardness.
PI, PET) to form a layer of dense metal-clad film. Taking copper-clad film as an example, copper ions are dissociated from targets and uniformly deposited on plastic substrates (e.g.
Top Nanometal Corp.’s roll-to-roll vacuum sputtering process and chemical process can produce a series of metal-clad thin films. Category: Industrial Material - Optolectronic
