Notes)
•
The 64-bit slot is an LSB first, two's complement output, and the 48-bit slot is an MSB first, two's complement output.
• GTOP is used to monitor the frame sync protection status. (High: sync protection window open.)
• XUGF is the negative pulse for the frame sync obtained from the EFM signal. It is the signal before sync protection.
• XPLCK is the inverse of the EFM PLL clock. The PLL is designed so that the falling edge and the EFM signal transition point
coincide.
•
GFS goes high when the frame sync and the insertion protection timing match.
•
RFCK is derived from the crystal accuracy, and has a cycle of 136µ.
• C2PO represents the data error status.
XRAOF is generated when the 32K RAM exceeds the ±28F jitter margin.
•
I/O
O Serial data output to SSP.
O Serial data latch output to SSP. Latched at the falling edge.
O Serial data transfer clock output to SSP.
Mirror signal input. Used when the number of tracks is 128 or more for the 2N-track jump and
I
M track move of the auto sequencer.
