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), ADAT optical
5.3 Transfer Modes: Resolution / Bits per Sample
16 bit 2 bytes
20 bit 3 bytes
20 bit 4 bytes
24 bit 3 bytes
24 bit 4 bytes MSB (stereo 8 bytes) (*)
32 bit 4 bytes
All the above formats are also available in Multi-Device mode (4 x stereo = 8 channels). The
Channel Interleave mode (1 x 8) provides the following resolutions:
16 bit 16 bytes (*)
24 bit 24 bytes
24 bit 32 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.
