1 Key Features

Following are the key features of JAPLL:

  • ITU-T SyncE compliant PLL.
  • Ability to hold outputs when no reference clock is available.
  • Ability to detect loss of signal and perform a Hitless clock switching (Phase of the output clock does not change when PLL switches input clocks).
  • Maintain frequency accuracy in the range of +/- 4.6 ppm.
  • Limited phase wander as measured by TDEV and MTIE.
  • Multi-rate protocol support such as:
    • Optical Transport Network (OTN)
    • Passive Optical Network (PON)
    • Common Public Radio Interface (CPRI) (Interface between Radio Equipment Control (REC) and Radio Equipment (RE))
    • Synchronous Ethernet (SyncE)
    • Video applications (High-Definition Serial Digital Interface (HD-SDI), 3 Gigabit Serial Digital Interface (3G-SDI), and so on)
