Notes)
•
•
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 136
µ
.
• C2PO represents the data error status.
• XRAOF is generated when the 32K RAM exceeds the
±
28F jitter margin.
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.
