NBXHBA019LN1TAG

Programmable Timers And Oscillators Overview

The NBXHBA019LN1TAG is a single-frequency crystal oscillator from ON Semiconductor's 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 deliver selectable output frequencies of 125 MHz or 250 MHz. The device features ultra-low jitter and phase noise characteristics, specifically 0.4 ps RMS phase jitter between 12 kHz and 20 MHz. It operates within a temperature range of -40°C to +85°C and provides total frequency stability of ±50 ppm. The component is housed in a hermetically sealed ceramic SMD package (CLCC-6, Case 848AB) and is RoHS compliant.

Programmable Timers And Oscillators Feature Summary

• LVPECL differential output with selectable frequencies: 125 MHz (default) or 250 MHz via FSEL pin
• Ultra-low jitter performance: 0.4 ps RMS phase jitter (12 kHz to 20 MHz)
• Hermetically sealed ceramic SMD package (CLCC-6, 5 mm x 7 mm)
• Total frequency stability of ±50 ppm over the 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 that the specific ordering suffix LN1TAG corresponds to the CLCC-6 package and tape & reel shipping quantity of 1000 units as documented for the NBXHBA019 series. Confirm availability status directly with the manufacturer, as certain variants within this family may require direct sales office contact for stock verification.

Programmable Timers And Oscillators Selection Notes

Select the NBXHBA019LN1TAG when a fixed 125 MHz LVPECL output is required. The FSEL pin defaults to logic HIGH (open circuit) to provide the 125 MHz frequency; pulling FSEL LOW selects 250 MHz. Ensure the design accommodates the 3.3 V ±10% supply voltage and terminates the LVPECL outputs with 50 Ω resistors to VTT = VDD - 2 V.

Programmable Timers And Oscillators Part Context

This component belongs to the NBXDBA019, NBXHBA019, and NBXSBA019 family of 3.3 V LVPECL clock oscillators. While sharing similar electrical specifications and package dimensions, these variants differ in internal configuration or availability. The NBXHBA019 specifically denotes the single-frequency variant optimized for standard clocking requirements within the PureEdge/C0116 portfolio.

Programmable Timers And Oscillators Replacement Considerations

Direct functional substitutes within the same family include NBXDBA019LN1TAG and NBXSBA019LN1TAG, which share identical electrical parameters and pinouts. Verify package compatibility and ensure the replacement part supports the required 125 MHz default output frequency if the FSEL pin is left unconnected.
