NBXSBA017LNHTAG

Programmable Timers And Oscillators Overview

The NBXSBA017LNHTAG is a hermetically sealed, single and dual frequency crystal oscillator from onsemi’s PureEdge clock family. It provides selectable 156.25 MHz or 312.5 MHz LVPECL differential outputs using a high Q fundamental mode crystal and PLL multiplier. The device operates at 3.3 V ±10% with an industrial temperature range of −40°C to +85°C. It features ultra-low jitter (0.4 ps RMS) and phase noise, ensuring precise timing for networking applications. Packaged in a 6-pin CLCC SMD format, it includes LVTTL/LVCMOS control inputs for output enable and frequency selection.

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'LNHTAG' against the manufacturer's current documentation to confirm shipping quantities and tape-and-reel specifications. Confirm that the industrial temperature grade (-40°C to +85°C) matches the design requirements. Ensure compatibility with the 3.3 V power supply and LVPECL termination standards before procurement.

Programmable Timers And Oscillators Selection Notes

Select this component when hermetic sealing and low aging are required for critical timing applications. The NBXSBA017 variant specifically defaults to 312.5 MHz but allows selection via the FSEL pin. Compare total frequency stability (+/-50 PPM) against commercial alternatives if tighter tolerance is needed. Ensure the PCB layout supports the 50 ohm termination to VDD-2V for optimal signal integrity.

Programmable Timers And Oscillators Part Context

This part belongs to the NBXDBB017/NBXDBA017/NBXHBA017/NBXSBA017 family. The NBXSBA017 is distinguished by its industrial temperature rating and default 312.5 MHz output capability, whereas NBXHBA017 is fixed at 156.25 MHz. The LNHTAG suffix indicates a 100-unit tape and reel packaging option.
