NBXDPA018LNHTAG

Programmable Timers And Oscillators Overview

The NBXDPA018LNHTAG is a dual-frequency crystal oscillator from onsemi’s PureEdge family, designed for 2.5 V and 3.3 V LVDS clock generation. It utilizes a high-Q fundamental crystal and PLL multiplier to provide selectable outputs of 155.52 MHz or 311.04 MHz with ultra-low jitter (0.5 ps RMS) and phase noise. The device features hermetically sealed ceramic SMD packaging in a 6-pin CLCC format. Key electrical parameters include a total frequency stability of ±50 ppm, an operating temperature range of −40°C to +85°C, and a power supply current of 85 mA typical at 2.5 V.

Programmable Timers And Oscillators Feature Summary

• Dual-frequency output selectable via FSEL pin: 155.52 MHz (default) or 311.04 MHz
• Ultra-low jitter performance: 0.5 ps RMS (12 kHz to 20 MHz)
• Hermetically sealed ceramic SMD package (CLCC-6) for reliability
• LVDS differential output with 100 Ω termination requirement

Programmable Timers And Oscillators Applications

• SONET line cards
• Networking equipment
• Optical systems

Programmable Timers And Oscillators Procurement Notes

Verify the LNHTAG suffix indicates a specific tape and reel quantity distinct from standard variants. Confirm RoHS compliance and Pb-free status through official documentation before procurement. Ensure the ordering suffix matches the required packaging specifications for automated assembly processes.

Programmable Timers And Oscillators Selection Notes

Select this component when low jitter and hermetic sealing are critical for SONET or optical applications. Verify that the system supports the required 2.5 V or 3.3 V supply rails. Ensure the PCB layout accommodates the 6-pin CLCC package dimensions and provides adequate thermal management for the specified operating temperature range.

Programmable Timers And Oscillators Part Context

This part belongs to the NBXDPA018 series within onsemi’s PureEdge clock family. It shares functional similarities with other models like NBXDPA017 and NBXDPA019 but offers specific frequency options and packaging configurations tailored for high-reliability networking and optical infrastructure.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include NBXDPA017LNHTAG (156.25/312.5 MHz) and NBXDPA019LNHTAG (125/250 MHz). Verify frequency compatibility and pinout alignment before substitution.
