29.3 Digital

• Clocks: Internal, MADI In, Word Clock In, optional Video and LTC 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 200 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)
