NBXMBB024LNHTAG

Programmable Timers And Oscillators Overview

The NBXMBB024LNHTAG is a single-frequency crystal oscillator (XO) from the PureEdge/C0116 family, designed for 2.5 V and 3.3 V LVPECL clock generation applications. It utilizes a high-Q fundamental mode crystal and a Phase Lock Loop (PLL) multiplier to generate a 622.08 MHz output with ultra-low jitter and phase noise. The device features hermetically sealed ceramic packaging and offers a total frequency stability of ±20 PPM within the commercial temperature range of 0°C to +70°C.

Programmable Timers And Oscillators Feature Summary

• LVPECL differential output with 0.5 ps RMS phase jitter (12 kHz to 20 MHz)
• Hermetically sealed 6-pin CLCC SMD package
• ±20 PPM total frequency stability in commercial temperature range
• Supports 2.5 V ±5% or 3.3 V ±10% operating supply voltage

Programmable Timers And Oscillators Applications

• SONET Line Card
• Networking Equipment
• Optical Systems

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'LNHTAG' corresponds to the CLCC-6 package with a tape and reel quantity of 100 units. Confirm RoHS compliance and Pb-free status as indicated by the 'G' marking. Ensure the application environment remains within the specified commercial temperature range of 0°C to +70°C for the guaranteed ±20 PPM stability specification.

Programmable Timers And Oscillators Selection Notes

Select this component when a fixed 622.08 MHz LVPECL clock source is required with strict jitter constraints. Compare against NBXSBA024LNHTAG if industrial temperature operation (-40°C to +85°C) with ±50 PPM stability is sufficient. Verify that the system power supply can accommodate either 2.5 V or 3.3 V inputs, as the device supports both ranges.

Programmable Timers And Oscillators Part Context

This part belongs to the NBXSBA024, NBXSBB024, and NBXMBB024 series. The 'M' in the model number designates the commercial temperature variant with ±20 PPM stability, distinct from the 'S' variant which provides ±50 PPM stability over an industrial temperature range. All variants share identical electrical characteristics and pinouts.

Programmable Timers And Oscillators Replacement Considerations

NBXSBB024LNHTAG serves as a direct functional equivalent with identical specifications and packaging. NBXSBA024LNHTAG is compatible but offers lower frequency stability (±50 PPM) and wider temperature range (-40°C to +85°C).

Programmable Timers And Oscillators FAQ

What is the default state of the OE (Output Enable) pin?

When left floating, the internal resistor pulls the OE pin to a logic HIGH level, keeping the output active.

How should the LVPECL outputs be terminated?

Outputs should typically be loaded with 50 Ω receiver termination resistors connected to VTT = VDD - 2 V.

What is the maximum RMS phase jitter specification?

The device guarantees an RMS phase jitter of 0.5 ps measured between 12 kHz and 20 MHz offset from the carrier.
