Color: As shown Material: PC Introduction: Using TI's PCM1795 chip, supporting 32BIT, 192K sampling rate, using IV and LPF circuits on Maranz machines, TI's NE5532 operational amplifier, Both PCM and DSD decoding modes can automatically change to appropriate parameters based on the input sampling rate When in PCM mode: Input digital signal supports I2S format and Left Justified format, default (I2S) When in DSD mode: supports DSD64, DSD128, DSD256 Digital input interface: PCM mode (DSD mode) 1. DSD0CE (set high level during DSD), not used during PCM 2.SDATA (DSD_L ) 3.BCLK (DSD_CLK) 4.LRCK (DSD_R) 5. MCLK (not used) 6.GND (GND) Dual power supply ports: +V ->DC+10-15V GND ->Ground V ------>DC -10~-15V Single power supply port: (If there is no suitable power supply, it can also be left unconnected and will automatically power from+V) VDD ->DC+5~10V GND ->Ground Color: As Shown Material: PC Package Contents: 1*decoding board Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
