NBSG111BA

Clock Buffers, Drivers Overview

The NBSG111BAEVB is an evaluation board for the NBSG111 GigaComm 1:10 clock data driver manufactured by onsemi. The board facilitates quick evaluation of the device, which selects between two inputs and fans out ten identical differential outputs using Reduced Swing ECL (RSECL) technology to ensure minimal noise and fast switching edges. Designed for high performance, it utilizes a two-layer construction with Rogers 6002 material and thick copper base. It supports operation up to 20 GHz, exceeding the device's 12 GHz specification, and enables time-domain measurements such as jitter and eye pattern generation, as well as frequency-domain gain and return loss analysis.

Clock Buffers, Drivers Feature Summary

• Supports evaluation of the NBSG111 1:10 differential clock/data driver with RSECL outputs
• Designed for operating frequencies up to 20 GHz using Rogers 6002 substrate
• Enables time-domain testing including jitter, output skew, rise/fall time, and eye patterns
• Facilitates frequency-domain S-parameter measurements (S21) via Vector Network Analyzer setup

Clock Buffers, Drivers Applications

• Evaluation of clock distribution networks in high-speed digital systems
• Characterization of jitter and signal integrity for SiGe drivers
• Development of microwave circuits requiring 1:10 fan-out capabilities
• Testing of Reduced Swing ECL interface performance

Clock Buffers, Drivers Procurement Notes

Verify that the specific order corresponds to the NBSG111BAEVB evaluation board rather than the NBSG111BA integrated circuit component. Confirm compatibility with required lab equipment, specifically split power supplies for VCC, VEE, and VTT connections, and matched high-speed cables with SMA connectors for proper termination and signal integrity during testing.

Clock Buffers, Drivers Selection Notes

Select this board when evaluating the NBSG111 device's performance at frequencies beyond its standard 12 GHz rating, up to 20 GHz. Ensure access to dual-output power supplies capable of providing the necessary split voltage rails (e.g., VCC=2.0V, VEE=-1.3V for 3.3V operation) and precision measurement instruments like sampling oscilloscopes or VNAs for accurate characterization.

Clock Buffers, Drivers Part Context

This evaluation board is specifically designed for the NBSG111, a 2.5V/3.3V SiGe differential 1:10 clock/data driver. The NBSG111BA suffix indicates the specific package variant (FCBGA-49) of the driver chip included or referenced for use with this board. The board serves as a hardware platform to validate the driver's specifications before integration into final designs.

Clock Buffers, Drivers Replacement Considerations

No direct replacement evaluation boards are documented for this specific part number. For alternative evaluation needs, consult onsemi documentation for other GigaComm series drivers or different fan-out ratios.
