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.
• C2PO represents the data error status.
• XROF is generated when the 32K RAM exceeds the ±28F jitter margin.
• C4M is a 4.2336MHz output that changes in CAV-W mode and variable pitch mode.
• FSTO is the 2/3 frequency-division output of the XTAI pin.
• SOUT is the serial data output inside the servo block.
• SOCK is the serial data readout clock output inside the servo block.
• XOLT is the serial data latch output inside the servo block.
