8A34042 Four-Channel Universal Frequency Translator

The 8A34042 Four-Channel Universal Frequency Translator is a highly integrated timing device that generates synchronous or asynchronous clocks from any of its reference inputs. The device can be is used in any synthesizer or jitter attenuator application, including Optical Transport Network (OTN), and Synchronous Ethernet (SyncE) systems. The internal System.

Features

▪ Close-in phase noise complies with Common Public Radio Interface (CPRI) frequency synchronization requirements ▪ Supports all ITU-T G.709 frequencies ▪ Meets OTN jitter and wander requirements per ITU-T G.8251 ▪ Four independent timing channels
• Each can act as a frequency synthesizer, jitter attenuator, Digitally Controlled Oscillator (DCO), or Digital Phase Lock Loop (DPLL)
• DPLL Digital Loop Filters (DLFs) are programmable with cut off frequencies from 1.1Hz to 22kHz
• Generates output frequencies that are independent of input frequencies via a Fractional Output Divider (FOD)
• Each FOD.
