digital output stage

 

 

The PCB will be delivered with all parts and connectors - not soldered!

The digital output that comes from the CD-Pro2 or another digital source looks often not as a square wave. This might be a problem of the output transformer.

Our digital outputstage will amply the signal coming from an s/pdif output too TTL signal level than stabilised over a LINE-driver and will be then divided into two separate signal paths with S/PDIF format and AES/EBU format. The output is galvanic decoupled by a special, hand made transformer with high-end powder ring core for digital signals and separate silver wire coils with PTFE isolation for AES/EBU and S/PDIF. With this output stage one can use longer lines without lost of performance and the signal was improved to a real square wave.

 

Hand made transformer for digital out and other applications:
The handmade  transformer has the following advantages: One can use special ferrite powder-ring-core and adapt the meandering of the coils exactly on the circuit.
We use a high quality silver wire with Teflon isolation for the coils. The coils will be glued on the ring.
The Teflon/Silver wire has the following advantages in the opposite of enamelled wire:
  • less microphone effects
  • The wire is more softly and thus better to process. It puts closely to powder ring. In connection with the gluing a compact unit results.
  • A firm magnetic coupling develops also, because nearly the entire magnetic flow implements both windings.

Technical data:

  • Measures of the PCB in as-delivered condition:  71 x43 mm
  • power supply 5 V

  • input 75 R

  • output 75 R for s/pdif and 47 R for AES/EBU

  • symmetric, unsymmetric output

  • s/pdif output format

  • AES/EBU output format

  • not soldered - only parts and PCB

Other crucial components

For each task we use special condensers:

  • For the signal path MKP/FKP condensers of Vishay with small tolerance and outstanding high-frequency response.
  • For the supporting of voltage supply not-inductive MKT condensers of Philips.
  • For the logic circuits special condensers of Panasonic, not-inductively and with special high frequency characteristics.
