The Ixia BOB10GE500 is a XAUI break-out box that disaggregates 10 Gigabit Ethernet XAUI signals into individual differential pairs, presented via 16 SMA coaxial connectors. This interface unit connects directly between Ixia 10GE load modules and devices requiring coaxial XAUI signal access, enabling detailed signal analysis and device control through integrated clock and MDIO management interfaces.
## Technical Specifications
**Signal Interface**
• XAUI signal aggregation and separation into differential pairs
• 16 SMA coaxial connectors for breakout connectivity
• 50 Ω ±5% impedance throughout signal path
**Clock Interface**
• Input: Female SMA, 50 Ω ±5%, DC coupled
• Maximum input: 6 V (DC plus half AC peak-to-peak)
• Output: Female SMA, 50 Ω ±5%, AC coupled
• Output amplitude: 0.9 Vpp minimum into 50 Ω (1.5 Vpp typical)
• Edge rates: 200 ps to 340 ps (20% to 80%) into 50 Ω
• Duty cycle: 45% to 55%
• Cycle-to-cycle jitter: 20 ps maximum (>1 kHz)
• Frequency: 156.25 MHz ±20 ppm (internal clock mode)
**Management**
• MDIO (Management Data Input/Output) interface for station management and device control
## Key Features
• Direct XAUI signal breakout into individual coaxial pairs
• High-speed clock distribution with tight jitter specifications
• Passive break-out architecture—no integrated transceivers
• MDIO support for manageable device control and monitoring
• 50 Ω matched impedance for signal integrity
## Typical Applications
• Protocol and physical layer testing of 10 Gigabit Ethernet devices
• Signal analysis at the XAUI interface level
• Device-under-test (DUT) connection and control in 10GE test environments
• MDIO device management in multi-port Ethernet test configurations
## Compatibility & Integration
The BOB10GE500 integrates with Ixia’s 10 Gigabit Ethernet load modules and operates with systems that implement XAUI interfaces. Load modules used with this break-out box support various transceiver types—including XENPAK and X2 formats—depending on the specific 10GE module configuration.
