NBXSBA019LNHTAG

Programmable Timers And Oscillators Overview

The NBXSBA019LNHTAG is a single and dual frequency crystal oscillator from the PureEdge/C0116 family, designed for 3.3 V LVPECL clock generation applications. It utilizes a high Q fundamental mode crystal and a Phase Lock Loop (PLL) multiplier to provide selectable 125 MHz or 250 MHz ultra-low jitter and phase noise LVPECL differential outputs. The device operates within a temperature range of -40°C to +85°C and features hermetically sealed ceramic SMD packaging. Key electrical characteristics include a power supply current of 78 mA typical, total frequency stability of ±50 ppm, and RMS phase jitter of 0.4 ps over the 12 kHz to 20 MHz bandwidth.

Programmable Timers And Oscillators Feature Summary

• Ultra-low jitter and phase noise performance with 0.4 ps RMS phase jitter (12 kHz to 20 MHz)
• Selectable output frequencies: 125 MHz (default) or 250 MHz via FSEL pin
• Hermetically sealed ceramic SMD package (CLCC-6, Case 848AB)
• LVPECL differential output with standard 50 ohm termination to VTT = VDD - 2 V

Programmable Timers And Oscillators Applications

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

Programmable Timers And Oscillators Procurement Notes

Verify that the ordering suffix LNHTAG corresponds to the CLCC-6 package in quantities of 100 units per tape and reel. Confirm RoHS compliance and Pb-free status as specified in the datasheet attributes. Ensure the application circuit supports the required 3.3 V ±10% power supply and proper LVPECL termination resistors to maintain signal integrity.

Programmable Timers And Oscillators Selection Notes

Select this component when an ultra-low jitter LVPECL clock source is required for high-speed networking or Infiniband applications. The FSEL pin allows dynamic selection between 125 MHz and 250 MHz outputs. Ensure the design accommodates the 78 mA typical supply current and provides adequate thermal management within the -40°C to +85°C operating range.

Programmable Timers And Oscillators Part Context

This part belongs to ON Semiconductor’s PureEdge/C0116 clock family, which provides accurate and precision clock solutions. It is functionally related to the NBXDBA019 and NBXHBA019 models, differing primarily in default output frequency configurations and specific pin assignments for the FSEL control.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include NBXDBA019LNHTAG and NBXHBA019LNHTAG. Verify that the substitute part matches the required output frequency (125 MHz vs 250 MHz) and package type before integration.
