29.3 Digital

• Clocks: Internal, MADI 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: about 30 dB (2.4 kHz)
• Effective clock jitter influence on DA conversion: near zero
• Provides nearly jitter-free word clock directly from the MADI input signal
• Input PLL ensures zero dropout, even at more than 100 ns jitter
• Supported sample rates: 28 kHz up to 105 kHz

29.4 MIDI

• 2 x MIDI I/O via breakout cable
• 1 x MIDI I/O via MADI
• PCI bus based hi-speed operation
• Separate 128 byte FIFO for input and output
• MIDI state machine in hardware for reduced interrupt request load
• Invisible transmission via User bit of channel 56 (up to 48 kHz)
• Invisible transmission via User bit of channel 28 (up to 96 kHz)
