NBXMBA024LNHTAG

Programmable Timers And Oscillators Overview

The NBXMBA024LNHTAG 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 SMD packaging and operates within an industrial temperature range of -40°C to +85°C. Key electrical parameters include a maximum RMS phase jitter of 0.7 ps (12 kHz to 20 MHz), a typical power supply current of 105 mA, and a start-up time of 5 ms.

Programmable Timers And Oscillators Feature Summary

• Generates a precise 622.08 MHz LVPECL differential output using a PLL multiplier and fundamental crystal.
• Ultra-low jitter performance with 0.5 ps typical RMS phase jitter (12 kHz to 20 MHz).
• Hermetically sealed 6-pin CLCC package (CASE 848AB) suitable for harsh environments.
• Industrial temperature operation (-40°C to +85°C) with ±50 ppm total frequency stability.

Programmable Timers And Oscillators Applications

• SONET Line Card
• Networking Equipment
• Optical Systems

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'LNHTAG' against official documentation to confirm the 100-unit tape and reel quantity and lead time requirements. Confirm that the 'M' designation in the part number aligns with the intended pinout configuration for the OE/NC pins as specified in the datasheet diagrams.

Programmable Timers And Oscillators Selection Notes

Select this component when a low-jitter 622.08 MHz clock source is required for SONET or optical networking interfaces. Ensure the design supports the 2.5 V or 3.3 V supply rails and provides adequate termination resistors (50 Ω to VDD - 2.0 V) for the LVPECL outputs. Verify thermal management capabilities given the 105 mA typical current draw.

Programmable Timers And Oscillators Part Context

This part belongs to the NBXSBA/NBXMBB series of clock oscillators. While the provided datasheet primarily details the NBXSBA024, NBXSBB024, and NBXMBB024 devices, the NBXMBA024 variant shares the same core architecture, frequency, and package type, differing primarily in pinout assignments for the OE and NC pins.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include NBXSBA024LNHTAG and NBXSBB024LNHTAG. Note that these variants may have different pin configurations for the Output Enable (OE) and No Connect (NC) pins compared to the NBXMBA024; verify pin compatibility before substitution.
