8A34043 Datasheet | Renesas

Overview The 8A34043 Four-Channel Universal Frequency Translator is a highly integrated timing device that generates synchronous or asynchronous clocks from its reference inputs. The device can be used 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 - 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 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 - Four differential / eight 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° - Two differential / four single-ended clock inputs - Support frequencies from 1k Hz to 1GHz - Any input can be mapped to any or all of the timing channels - Redundant inputs frequency independent of each other - Any input can be designated as external frame/sync pulse of PPES (pulse...
