NBXHBA019LNHTAG

Programmable Timers And Oscillators Overview

The NBXHBA019LNHTAG is a single-frequency crystal oscillator from the PureEdge/C0116 family, manufactured by onsemi. It provides a selectable 125 MHz or 250 MHz LVPECL differential output using a high Q fundamental mode crystal and PLL multiplier. The device operates at 3.3 V ±10% with ultra-low jitter (0.4 ps RMS) and phase noise. It features hermetically sealed ceramic SMD packaging in a 5 mm x 7 mm CLCC-6 package. Key control inputs include OE for tri-state functionality and FSEL for frequency selection.

Programmable Timers And Oscillators Feature Summary

• LVPECL Differential Output with 0.4 ps RMS jitter (12 kHz–20 MHz)
• Selectable Frequency: 125 MHz (default/open) or 250 MHz via FSEL pin
• Hermetically Sealed Ceramic SMD Package (CLCC-6)
• Total Frequency Stability of ±50 ppm over operating temperature range

Programmable Timers And Oscillators Applications

• Ethernet and Gigabit Ethernet systems
• Infiniband interconnects
• Telecommunications base stations

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'LNHTAG' against current manufacturer availability lists, as documentation indicates potential supply constraints for certain variants within this family. Confirm RoHS compliance and Pb-free status during procurement. Ensure tape and reel specifications match the required quantity of 100 units per reel.

Programmable Timers And Oscillators Selection Notes

Select NBXHBA019LNHTAG when a fixed 125 MHz output is required; the 'H' designation typically indicates the 125 MHz variant compared to the 'S' variant which defaults to 250 MHz. Use the FSEL pin to switch between 125 MHz and 250 MHz if flexibility is needed. Ensure the application supports LVPECL termination with VTT = VDD - 2 V. Verify thermal management requirements for the CLCC-6 package.

Programmable Timers And Oscillators Part Context

This component belongs to the NBXxBA019 series, which includes NBXDBA019, NBXHBA019, and NBXSBA019. These devices share the same core architecture but differ in default output frequencies and pin configurations. The NBXHBA019 specifically targets applications requiring precise 125 MHz clocking with the option to scale to 250 MHz.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include NBXSBA019LNHTAG (250 MHz default) and NBXDBA019LNHTAG (dual frequency). Cross-vendor equivalents require careful evaluation of LVPECL compatibility, jitter performance, and hermetic sealing requirements.
