5. Technical Specifications

5.1 Digital

• Low jitter S/PDIF: < 5 ns in PLL mode (44.1 kHz, optical in)

• Ultra-low jitter ADAT: < 2 ns in PLL mode (44.1 kHz, optical in)

• Input PLL ensures zero dropout, even at more than 40 ns jitter

• Bitclock PLL for trouble-free varispeed operation in ADAT mode

• High-sensitivity input stage (< 0.2 Vss input level)

• Output voltage 0.8V (consumer mode, phono) or 2.3V (professional mode)

• Sample frequencies: 32 / 44.1 / 48 / 88.2 / 96 kHz and variable (word clock) supported

5.2 Digital Interface

• Phono input and output ground-free transformer coupled

• Connectors: optical (TOSLINK), phono, internal (CD-ROM/Sync in, Sync out)

• Clocks: ADAT Sync In

• Formats: S/PDIF (Consumer and Professional), ADAT optical

5.3 Transfer Modes: Resolution / Bits per Sample

• 32 bit, 4 byte (stereo 8 byte)

This format is compatible with 16-bit and 20-bit. Resolutions below 24-bit are handled by the

audio application. The card works internally with 32-bit data, but audio data transfer is limited to

24-bits.
