NBXSBA046LNHTAG

Overview

The NBXSBA046LNHTAG is a single-frequency crystal oscillator (XO) from onsemi’s PureEdge/C0116 family, generating a 172.50 MHz LVPECL differential output. It utilizes a high-Q fundamental mode crystal and a Phase Lock Loop (PLL) multiplier to achieve ultra-low jitter and phase noise. 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 hermetically sealed ceramic packaging in a 6-pin CLCC (Case 848AB) format, measuring 5 mm x 7 mm. Total frequency stability is specified at ±50 ppm over the operating temperature range of -40°C to +85°C.

Feature Summary

• LVPECL Differential Output: Provides non-inverted and inverted clock signals with an output voltage amplitude of 700 mV.
• Ultra-Low Jitter: Achieves 0.5 ps RMS phase jitter (12 kHz to 20 MHz) and -159 dBc/Hz phase noise at 10 MHz offset.
• Hermetically Sealed Package: Encased in a robust ceramic SMD package suitable for harsh environments.
• Precise Frequency Stability: Maintains ±50 ppm total frequency stability, including aging specifications.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'H' corresponds to the 100-unit tape and reel quantity 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 provides adequate thermal management for the ceramic package.

Selection Notes

Select this component when a fixed 172.50 MHz LVPECL signal is required with stringent jitter constraints. The hermetically sealed ceramic package is appropriate for applications demanding long-term reliability and environmental resistance compared to standard plastic packages. Verify that the system power rails align with the 2.5 V or 3.3 V operational requirements.

Part Context

This part belongs to the NBXSBA series of standard clock oscillators manufactured by onsemi. It is designed as a drop-in replacement for legacy crystal oscillators in high-performance networking and storage architectures where low phase noise is critical for signal integrity.

Replacement Considerations

Direct pin-compatible replacements within the same family include NBXSBA046LN1TAG, which shares identical electrical characteristics but is supplied in 1,000-unit tape and reel quantities instead of 100 units.
