24-bit 384khz PCM NOS R2R high-precision resistance network decoder board fever

Description

24-bit 384khz PCM NOS R2R high-precision resistance network decoder board fever level
Description
Description:
Dimensions: length 160mm, width 123mm, excluding the protruding part of the interface
Voltage: DC voltage +5v logic circuit power supply
DC voltage +15v 0v -15v analog amplifier circuit power supply (one channel, one channel, separate power supply)
The power supply mode cannot be directly connected to the transformer, and the rectifier voltage stabilizer board should be used for power supply.
Signal input: 4-wire I2S (Philips IIS format) does not support left-justified, right-justified GND BCK LRCK DATA
Supports the highest sampling rate and tested PCM384KHZ to work normally, and does not support the DSD format.
Output: Single-ended (RCA) L-OUT and R-OUT
Balanced (XLR) XLR-L +/- and XLR-R +/-
Output analog signal level: single-ended 2.5vRMS
Balanced 4.8vRMS
The entire decoder board uses CPLD as data processing. The advantage is due to the fact that CPLD is parallel processing and does not have a serial processing process like peripheral logic chips. The delay between all gates will accumulate. The delay to the last data is very large. The resulting signal jitter cannot be ignored. Therefore, the R2R DAC developed by CPLD has advantages.
This decoder board has mid-tone accuracy, deep bass diving, and high-tone accuracy. The overall experience shows that the degree of separation is better than that of the integrated IC solution. (Under the premise of cooperating with our USB interface card)
This is a bold work, manufactured by SMT industrialization, the components are neat and beautiful, and the solder joints are full and shiny. The use of SMT production reduces the manual reclaiming process and avoids the situation of soldering wrong components. Greatly improve the accuracy and precision of decoding. Escort for the good voice. In terms of price, it is deeply rooted in the hearts of the people. At a price close to the people, enthusiasts can enjoy the treatment of big factory machines.
