NBXSBA021LN1TAG

Programmable Timers And Oscillators Overview

The NBXSBA021LN1TAG is a single frequency crystal oscillator (XO) from onsemi’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 a 266.667 MHz output with ultra-low jitter and phase noise. The device features hermetically sealed ceramic SMD packaging in a 5 mm x 7 mm CLCC-6 footprint. It operates within a temperature range of -40°C to +85°C and provides a total frequency stability of ±50 PPM.

Programmable Timers And Oscillators Feature Summary

• LVPECL differential output with 0.4 ps RMS phase jitter (12 kHz to 20 MHz)
• Hermetically sealed ceramic SMD package (CLCC-6)
• Built-in Output Enable (OE) control pin
• ±50 PPM total frequency stability over operating temperature

Programmable Timers And Oscillators Applications

• Servers
• Fully Buffered DIMM

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation before procurement. The 'LN1' suffix indicates standard tape and reel packaging containing 1,000 units per reel. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer's sales office, as availability may vary.

Programmable Timers And Oscillators Selection Notes

Select the NBXSBA021LN1TAG when a 266.667 MHz LVPECL signal with ±50 PPM stability is required. For tighter stability requirements of ±20 PPM, consider the NBXSBB021 variant. Ensure the design accommodates the 3.3 V power supply and proper termination resistors (50 Ω to VTT = VDD - 2 V) for the LVPECL outputs.

Programmable Timers And Oscillators Part Context

This component belongs to the PureEdge/C0116 clock family, which provides precision clock solutions using fundamental crystals and PLL multipliers. The NBXSBA021 series is specifically engineered for low jitter performance in high-speed digital systems requiring reliable clock distribution.

Programmable Timers And Oscillators Replacement Considerations

The NBXSBB021LN1TAG serves as a direct functional substitute if higher frequency stability (±20 PPM vs. ±50 PPM) is needed. Other variants in the NBXSBA021 family, such as NBXSBA021LNHTAG, offer different packaging quantities but maintain identical electrical characteristics.
