NBXSBA017LN1TAG

Programmable Timers And Oscillators Overview

The NBXSBA017LN1TAG is a single-frequency crystal oscillator from onsemi's PureEdge family, designed for 3.3 V LVPECL clock generation. It utilizes a high Q fundamental mode crystal and a Phase Lock Loop (PLL) multiplier to deliver selectable output frequencies of 156.25 MHz or 312.5 MHz. The device features ultra-low jitter and phase noise characteristics, with an RMS phase jitter of 0.4 ps between 12 kHz and 20 MHz. It operates within a temperature range of -40°C to +85°C and provides a total frequency stability of ±50 ppm. The component is housed in a hermetically sealed ceramic SMD package.

Programmable Timers And Oscillators Feature Summary

• LVPECL differential output with selectable frequencies of 156.25 MHz (default) or 312.5 MHz via FSEL pin
• Ultra-low jitter performance: 0.4 ps RMS phase jitter (12 kHz to 20 MHz)
• Hermetically sealed ceramic CLCC-6 package (CASE 848AB)
• Total frequency stability of ±50 ppm over the industrial temperature range (-40°C to +85°C)

Programmable Timers And Oscillators Applications

• Networking equipment
• 10 Gigabit Ethernet systems

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm shipping quantity and packaging details. The LN1TAG suffix indicates a tape and reel configuration with a standard factory quantity of 1,000 units. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement.

Programmable Timers And Oscillators Selection Notes

Select this component when a fixed 312.5 MHz LVPECL output is required, as indicated by the 'S' suffix in the base model number. Ensure the application supports the 3.3 V ±10% operating voltage range. For designs requiring 156.25 MHz, consider the NBXDBA017 variant or utilize the FSEL pin logic if the specific part allows frequency selection, though the NBXSBA017 is optimized for the higher frequency.

Programmable Timers And Oscillators Part Context

This device belongs to the NBXDxx017 series of crystal oscillators, which also includes models like NBXDBB017 and NBXHBA017. These components share the same CLCC-6 package and general electrical architecture but differ in frequency stability specifications and default output frequencies. The NBXSBA017 specifically targets applications needing the 312.5 MHz rate with industrial-grade stability.

Programmable Timers And Oscillators Replacement Considerations

The NBXDBA017LN1TAG serves as a functional substitute if the system can operate at 156.25 MHz instead of 312.5 MHz. Both parts share identical pinouts, packages, and power requirements. Verify that the target frequency matches the design requirements before swapping.
