MIDIIN
MIDI Serial Data Input
This signal is part of the standard 2 wire MIDI interface. This input receives MIDI data at a rate
of 31.25Kbaud. Optical isolation is required.
MIDIOUT
MIDI Serial Data Output
This signal is part of the standard 2 wire MIDI interface. This output transmits MIDI data at a
rate of 31.25Kbaud. Optical isolation is required.
SYNC
AC’97 Codec Synchronization/Frame Output
This signal is used to frame the tag packet from the AC link designer from the SAA7785 chip.
BIT_CLK
AC’97 Data Bit Clock
This signal is used to clock synchronous data on the AC link interface.
