NBXSBA045LN1TAG

Programmable Timers And Oscillators Overview

The NBXSBA045LN1TAG is a single-frequency crystal oscillator (XO) from onsemi’s PureEdge/C0116 clock family, designed for 2.5 V or 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 precise 345.00 MHz output with ultra-low jitter and phase noise. The device features hermetically sealed ceramic SMD packaging in a 6-pin CLCC format, ensuring reliability in demanding environments. Key electrical specifications include a total frequency stability of ±50 ppm, an RMS phase jitter of 0.4 ps between 12 kHz and 20 MHz, and a power supply current of approximately 95 mA.

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'LN1TAG' corresponds to the 1000-unit tape and reel configuration as documented in the datasheet. Confirm that the application environment supports the specified operating voltage ranges of 2.5 V ±5% or 3.3 V ±10%. Ensure proper termination resistors are used for the LVPECL outputs to maintain signal integrity and meet the specified jitter performance metrics.

Programmable Timers And Oscillators Selection Notes

Select this component when a fixed 345.00 MHz frequency with LVPECL outputs is required. Consider the ±50 ppm frequency stability and 0.4 ps jitter performance for high-speed digital interfaces. The hermetically sealed CLCC package is appropriate for applications requiring enhanced environmental protection compared to standard plastic packages. Verify compatibility with the system's power supply voltage levels before integration.
