NBSG111BAHTBG

Clock Buffers, Drivers Overview

The NBSG111BAEVB is an evaluation board for the NBSG111 GigaComm 1:10 clock data driver. It facilitates testing of a device that selects between two inputs and fans out ten identical differential outputs using Reduced Swing ECL (RSECL). The board supports operation at 3.3 V (VEE = -1.3 V) and 2.5 V (VEE = -0.5 V) with split power supplies where VTT equals system ground. Designed for high performance, it utilizes Rogers 6002 material to support frequencies up to 20 GHz, enabling measurements such as jitter, output skew, gain/return loss, eye pattern generation, and frequency response.

Clock Buffers, Drivers Feature Summary

• Supports 1:10 fan-out of differential RSECL signals from dual selectable inputs
• Compatible with 3.3 V and 2.5 V power supply configurations
• Constructed on Rogers 6002 substrate for microwave performance up to 20 GHz
• Enables time domain and frequency domain characterization including S21 and jitter

Clock Buffers, Drivers Applications

• Evaluation of clock distribution networks in high-speed digital systems
• Testing of differential signal integrity and eye diagram analysis
• Characterization of return loss and gain performance via Vector Network Analyzer
• Development of gigabit serial communication links requiring low jitter

Clock Buffers, Drivers Procurement Notes

Verify the specific revision status of the NBSG111BAEVB manual against current product offerings. Confirm that the required laboratory equipment, such as split power supplies and high-bandwidth oscilloscopes, matches the setup specifications detailed in the documentation. Ensure compatibility with the NBSG111BA component package when sourcing replacement drivers for the board.

Clock Buffers, Drivers Selection Notes

Select this board for validating the NBSG111 driver's performance in both single-ended and differential modes. Use the 3.3 V configuration for standard lab setups or the 2.5 V setup if bias tees are available for frequency domain tests. Ensure signal generators provide the specified 500 mV amplitude and 660 mV offset for optimal RSECL operation.

Clock Buffers, Drivers Part Context

This evaluation kit corresponds to the NBSG111BA, a SiGe differential 1:10 clock/data driver housed in an 8x8 mm FCBGA-49 package. The board serves as a reference design to demonstrate the capabilities of the GigaComm technology, specifically focusing on minimal noise and fast switching edges provided by the RSECL output architecture.

Clock Buffers, Drivers Replacement Considerations

The NBSG111BAEVB is designed exclusively for the NBSG111BA component. No alternative driver ICs are documented as compatible substitutes within the provided manual.
