LMK5B12204RGZR is a four-output network synchronizer and jitter cleaner built around a DPLL and two APLLs, including a low-jitter BAW VCO clock domain.

Best for

  • SyncE and network timing equipment
  • IEEE 1588 PTP-assisted clock control
  • Ethernet and OTN clock cleanup
  • Low-jitter 156.25 MHz and 312.5 MHz SerDes clock generation

Avoid if

  • A fixed-function oscillator is sufficient
  • The design cannot support PLL programming and validation

Check before use

  • Confirm reference and XO frequency plan
  • Select correct input and output termination
  • Confirm VDDO voltage and output format
  • Review holdover and hitless-switching settings
