Notes)
• PCMD is a MSB first, two's complement output.
• GTOP is used to monitor the frame sync protection status. (High: sync protection window released.)
• XUGF is the frame sync obtained from the EFM signal, and is negative pulse. It is the signal before sync
protection.
• XPCK is the inverse of the EFM PLL clock. The PLL is designed so that the falling edge and the EFM signal
transition point coincide.
• The GFS signal goes high when the frame sync and the insertion protection timing match.
• RFCK is derived from the crystal accuracy, and has a cycle of 136µs. (during normal speed)
• C2PO represents the data error status.
• XROF is generated when the 32K RAM exceeds the ±28F jitter margin.
