Note) • The PCMD is 2`s complement output of the MSB first.
• The GTOP is to monitor the protection status of the frame sync. ("H": sync protection window open)
• The XUGF is the frame sync obtained by the EFM signal and negative pulse. Signal before sync protection
• The XPCK is the inverted signal of the EFM PLL clock. The PLL is made so that the trailing edge and the changing point of the EFM signal agree.
• The GFS becomes "H" when the frame sync and inner protection timing agrre.
• The RFCK is the signal of 136 !!s cycle from the X`tal accuracy.
• The C2PO is the signal to indicate the error status of the data.
• The XROF is the signal when the 16K RAM exceeds the jitter margin of +/- 4frames.
