STEREOPHONE CODE WITH S / PDIF INTERFACE - PROGRAMMED SYSTEM

Producer: AVT

Presented codec with S / PDIF interface is characterized by the possibility of quite flexible configuration and, consequently, many own tests and can be a contribution to a deeper interest in digital processing of audio signals. The device is designed based on the Philips UDA1355 chip. It can work in many configurations set in static mode (without a UC) as well as with a microprocessor controller. It has four selectable internal S / PDIF input selector, S / PDIF output, built-in A / CD and D / A converters. The structure also includes a DSP processor that allows you to adjust the level of the A / D converter's signal output as well as the level and color of the D / A converter signal. A very important advantage is the ability to create two independent signal paths, each with a different clock frequency.

The device is especially recommended for advanced electronics-audiophiles

Selected parameters:

  • stereo analog input
  • amplification of the input amplifier regulated in the range of 0-24
  • range of digital output level adjustment from A / D converter 63,5dB - 24dB with a step of 0.5dB
  • types of switchable inputs: I2S with programmable data format, stereo analog input
  • built-in interpolator filter - DSP processor
  • range of bass adjustment 0 to +18 (+24) dB, high tones 0 to + 6dB
  • independent adjustment of the level of the output signal in each channel
  • digital mixer of two signals
  • extensive programmable system clock generation
  • power supply - 230 Vac
  • programmed layout
