Independent output board, support coaxial RS422 0.5V level, TTL level, optical output, AES balanced output
The input SPDIF sampling rate supports 44.1KHz~192KHz, and the optical fiber supports the maximum output of 96K SPDIF
All capacitors use Murata X7R COG material capacitors to ensure signal quality
176.4KHz signal output by the clock board
Comparison of output board effects, the yellow line is the input signal, and the blue line is the output signal
The following measures the output waveform of TTL COAX AES interface to 44.1K 96K 192K signal:
SPDIF audio source: USD01 RCA output port
Oscilloscope: DS1102E
Description: The yellow line is the input signal, the blue line is the output signal
TTL:
44.1K
Note: The TTL output is 0.01uF (X7R) capacitively coupled output, the load is 10K (see the circuit diagram for details), the waveform will be ideal, and the ringing is also handled very well
COAX:
44.1K
Output board interface description:
1. Output support coaxial, optical fiber output; it is recommended to use 50 ohm BNC coaxial transmission
2. Input voltage DC 5V
3. Support 44.1K~192K SPDIF signal
4. Using DS8921 as input and output buffer
5. Support TTL level and RS422 level input
