WAN PLLs (PDH and SONET/SDH)

IDT’s WAN (Wide Area Network) PLLs are designed for synchronization of PDH, SONET/SDH and TDM equipment and interfaces. These devices comply with ITU-T recommendations for SECs (SDH Equipment Clocks); as well as Telcordia and ATIS/ANSI requirements for stratum 4, stratum 4E, stratum 3 and SONET minimum clock. IDT WAN PLLs provide functions such as selectable loop filters, holdover, hitless reference switching, phase slope limiting and clock redundancy.
