Italian USB Digital Interface Upgraded Version Optical Interface Transmitter Module for I2S/Coaxial/Optical/Analog Conversion
Difference of two versions:
- Standard version: pure copper gold-plated RCA
- Upgraded version: advanced gold-plated RCA
Description:
- All chips used on the board are imported and original, and two sets of LDOs are designed to separately power the analog and digital circuits. Large capacity solid-state capacitors and tantalum capacitors are used for filtering and decoupling to ensure stable and clean power supply, effectively improving the overall output signal-to-noise ratio.
Features:
- For PCM9211 chip is comparable to original professional level digital audio transceiver chip for TI; Supports up to 216K sampling rate, with ultra-low jitter function and performance of coaxial transceiver clock <50RMS.
- Original SN74HC245 high speed bidirectional buffer chip can effectively ensure signal transmission without distortion, while greatly enhancing the input and output driving capabilities of I2S/DSD signals.
- It uses a high-quality 4-bit toggle switch to set the conversion mode and output data bit depth, 1/2 bit to set the conversion mode, and 3/4 bit to set the data output bit depth in the current working mode.
- It uses for SiTime industrial grade programmable digital silicon crystal oscillator, which has ultra-low jitter and extremely low phase noise, and is recognized as the most ideal clockwise device by the industry.
Package Included:
- 1 x D1 Format Conversion Board
