8A34004E-000NBG is a Synchronization Management Unit for packet based and physical layer based equipment synchronization.
8A34004E-000NBG is a highly integrated device that provides tools to manage timing references, clock sources, and timing paths for IEEE 1588 and Synchronous Ethernet based clocks.
Feature
Two independent timing channels
4 Differential / 8 LVCMOS outputs
2 differential / 4 single-ended clock inputs
Reference monitors qualify/disqualify references depending on LOS, activity, frequency monitoring, and/or LOS input pins
Automatic reference selection state machines select the active reference for each DPLL based on the reference monitors, priority tables, revertive / non-revertive, and other programmable settings
System APLL operates from fundamental-mode crystal: 25MHz to 54MHz or from a crystal oscillator
System DPLL accepts an XO, TCXO, or OCXO operating at virtually any frequency from 1MHz to 150MHz
DPLLs can be configured as DCOs to synthesize Precision Time Protocol (PTP) / IEEE 1588 clocks
DPLL Phase detectors can be used as Time-to-Digital Converters (TDC) with precision below 1ps
Supports 1MHz I2C or 50MHz SPI serial processor ports
1 JTAG Boundary Scan
-40°C to +85°C operating temperature range
7mm x 7mm VFQFPN48 package
Applications
Core and access IP switches / routers
Synchronous Ethernet equipment
Telecom Boundary Clocks (T-BCs) and Telecom Time SlaveClocks (T-TSCs) according to ITU-T G.8273.2
10Gb, 40Gb, and 100Gb Ethernet interfaces
Central Office Timing Source and Distribution
Wireless infrastructure for 4.5G and 5G network equipment
