5. Technical Specifications

5.1 Digital

• Low Jitter Design: < 3 ns in PLL mode (44.1 kHz, optical input)

• Supported sample rates: 32 kHz, 44.1 kHz, 48 kHz, 25 kHz-60 kHz via AutoSync

• High sensitive input stage (< 0.2Vss input level)

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

• Output voltage Consumer 0.8 V, Professional 1.6 V

• Supports all known formats mono/stereo from 16 to 24 bit

5.2 Digital Interface

• Inputs and outputs ground-free transformer coupled

• Connectors: optical (TOSLINK), coaxial (phono), internal (CD-ROM/Sync-In, Sync-Out)

• Formats: SPDIF, AES/EBU (Consumer/Professional)

5.3 Transfer Modes: Resolution / Bits per Sample

• 16 bit 2 bytes (stereo 4 bytes) (*)

• 20 bit 3 bytes MSB (stereo 6 bytes)

• 20 bit 4 bytes MSB (stereo 8 bytes) (*)

• 24 bit 3 bytes (stereo 6 bytes)

• 24 bit 4 bytes MSB (stereo 8 bytes) (*)

• 32 bit 4 bytes (stereo 8 bytes) (*)

* The indicated modes are directly supported by the hardware and therefore work in 32 bit hi-speed transfer mode. The other

modes (so called 'packed byte' formats) are queued up to 32 bit data packets by special copy routines in the driver. These

routines are written in Assembler, causing no measureable system load. The supported modes with other Operating Sys-

tems than Windows depend on the OS and/or the corresponding drivers.
