8A34045 - Two-Channel Universal Frequency Translator

Description

The 8A34045 Two-Channel Universal Frequency Translator is a highly integrated timing device with two Digital PLL (DPLL) channels, DPLL/DCO_[0..1]; and six Digitally Controlled Oscillator (DCO) channels, DCO_[2..7].

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.
  • Two independent DPLL/DCO 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 1.1.

Two-Channel Universal Frequency Translator 8A34045 Datasheet Overview The 8A34045 Two-Channel Universal Frequency Translator is a highly integrated timing device with two Digital PLL (DPLL) channels and six Digitally Controlled Oscillator (DCO) channels. The DPLLs can lock to external references or operate in free run, and can also be configured as DCOs. Each DCO can be synchronized by any of the DPLLs or they can operate in free run. The DCOs can alternatively be controlled by an external algorithm for Optical Transport Network (OTN) applications. Typical Applications ▪ Core and access IP switches / routers ▪ Synchronous Ethernet equipment ▪ 10Gb, 40Gb, and 100Gb Ethernet interfaces ▪ Wireless infrastructure for 4.
