31.2 MIDI
• 2 x MIDI I/O via 5-pin DIN jacks
• Galvanically isolated by optocoupled input
• Hi-speed mode: Jitter and response time typically below 1 ms
• Separate 128 byte FIFOs for input and output
31.3 Digital
• Clocks: Internal, SPDIF In, ADAT In, word clock in
• Low Jitter Design: < 1 ns in PLL mode, all inputs
• Internal clock: 800 ps Jitter, Random Spread Spectrum
• Jitter suppression of external clocks: > 30 dB (2.4 kHz)
• Effective clock jitter influence on AD and DA conversion: near zero
• PLL ensures zero dropout, even at more than 100 ns jitter
• Digital Bitclock PLL for trouble-free varispeed ADAT operation
• Supported sample rates: 28 kHz up to 200 kHz
31.4 Digital Inputs
Word Clock
• BNC, not terminated (10 kOhm) or internally terminated (75 Ohms)
• Automatic Double/Quad Speed detection and internal conversion to Single Speed
• SteadyClock guarantees super low jitter synchronization even in varispeed operation
• Not affected by DC-offsets within the network
• Signal Adaptation Circuit: signal refresh through auto-center and hysteresis
• Overvoltage protection
• Level range: 1.0 Vpp – 5.6 Vpp
• Lock Range: 27 kHz – 200 kHz
• Jitter when synced to input signal: < 1 ns
• Jitter suppression: > 30 dB (2.4 kHz)
