NBXSBA031LN1TAG

Programmable Timers And Oscillators Overview

The NBXSBA031LN1TAG is a single-frequency crystal oscillator (XO) from onsemi’s PureEdge family, generating a 340.00 MHz LVPECL differential output. It utilizes a high-Q fundamental mode crystal and a Phase Lock Loop (PLL) multiplier to achieve ultra-low jitter of 0.4 ps RMS (12 kHz–20 MHz). The device operates on a 2.5 V ±5% or 3.3 V ±10% supply with a typical current draw of 95 mA. It features a hermetically sealed ceramic CLCC-6 package, ensuring total frequency stability of ±50 ppm over the -40°C to +85°C operating range.

Programmable Timers And Oscillators Feature Summary

• Generates 340.00 MHz LVPECL differential clock signals using a PLL multiplier and fundamental crystal.
• Ultra-low phase noise and jitter performance: 0.4 ps RMS (12 kHz–20 MHz) and -155 dBc/Hz at 10 MHz offset.
• Hermetically sealed ceramic SMD package (CLCC-6) compliant with MIL-STD-833 mechanical standards.
• Total frequency stability of ±50 ppm guaranteed for 10 years, including initial stability and aging.

Programmable Timers And Oscillators Applications

• Networking equipment requiring precise timing references.
• Storage systems utilizing high-speed data interfaces.
• Wireless radio communications infrastructure.

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'LN1TAG' corresponds to the 1000-unit tape and reel packaging configuration. Confirm that the required frequency stability meets the ±50 ppm specification for the target application environment. Ensure the design accommodates the 95 mA typical power supply current and the recommended 50 Ω termination to VTT = VDD - 2.0 V for proper LVPECL signal integrity.

Programmable Timers And Oscillators Selection Notes

Select this component when a fixed 340.00 MHz LVPECL clock source is required with strict jitter constraints. The hermetically sealed ceramic package makes it suitable for harsh environments where MIL-STD-833 compliance is necessary. Compare against other PureEdge models if different frequencies or lower power consumption are needed, as this device draws approximately 95 mA.

Programmable Timers And Oscillators Part Context

This part belongs to the NBXSBA series of high-performance clock oscillators designed for networking and storage applications. It shares the same CLCC-6 package form factor and LVPECL output architecture as related parts like the NBXSBA030 (175 MHz) and NBXSBA025 (425 MHz), allowing for potential pin-compatible design variations across different system clock requirements.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes within the same family include the NBXSBA030LN1TAG (175 MHz) and NBXSBA025LN1TAG (425 MHz), provided the frequency difference is acceptable. For non-ceramic alternatives, verify if standard RoHS-compliant packages meet the environmental requirements, though hermetic sealing is unique to this specific package type.
