8-Channel Universal Frequency Translator 8A34041 Datasheet Overview The 8A34041 8-Channel Universal Frequency Translator is a highly integrated timing device that generates synchronous or asynchronous clocks from its reference inputs. The device is usable in any synthesizer or jitter attenuator application, including Optical Transport Network (OTN) and Synchronous Ethernet (Sync E) systems. Typical Applications - Core and access IP switches / routers - Synchronous Ethernet equipment - 10Gb, 40Gb, and 100Gb Ethernet interfaces - Wireless infrastructure for 4.5G and 5G network equipment - OTN Muxponders and line cards Features - Close-in phase noise plies with mon 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 - Eight 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 22k Hz - Generates output frequencies that are independent of input frequencies via a Fractional Output Divider (FOD) - Each FOD supports output phase tuning with 50ps resolution - 12 Differential / 24 LVCMOS outputs - Frequencies from 0.5Hz to 1GHz (250MHz for LVCMOS) - Jitter below 150fs RMS (10k Hz to 20MHz) - LVCMOS, LVDS, LVPECL, HCSL, CML, SSTL, and HSTL output modes supported - Differential output swing is selectable: 400m V / 650m V / 800m V / 910m V - Independent output voltages of 3.3V, 2.5V, or 1.8V - LVCMOS additionally supports 1.5V or 1.2V - The clock phase of each output is individually programmable in 1ns to 2ns steps with a total range of ±180° - 8 differential / 16 single-ended clock...
