NBXHGA053LNHTAG

Programmable Timers And Oscillators Overview

The NBXHGA053LNHTAG is a single-frequency crystal oscillator (XO) from onsemi’s PureEdge/C0116 family, designed for 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 50.00 MHz output with ultra-low jitter and phase noise. The device features hermetically sealed ceramic SMD packaging in a 6-pin CLCC format (7 mm x 5 mm). Key electrical specifications include a total frequency stability of ±50 PPM, an operating temperature range of -40°C to +85°C, and an RMS phase jitter of 0.8 ps within the 12 kHz to 20 MHz bandwidth.

Programmable Timers And Oscillators Feature Summary

• LVPECL Differential Output: Provides non-inverted and inverted clock signals with typical rise/fall times of 400 ps.
• Ultra-Low Jitter: Achieves 0.8 ps RMS phase jitter (12 kHz–20 MHz) and -164 dBc/Hz phase noise at 10 MHz offset.
• High Stability: Ensures ±50 PPM total frequency stability over the specified temperature range.
• Hermetic Packaging: Encased in a robust 6-pin Ceramic Leadless Chip Carrier (CLCC) package suitable for harsh environments.

Programmable Timers And Oscillators Applications

• Networking equipment requiring precise clock synchronization
• Telecommunications infrastructure systems
• General-purpose digital logic timing circuits

Programmable Timers And Oscillators Procurement Notes

Verify the ordering suffix 'LNHTAG' corresponds to the specific tape and reel quantity of 100 units per reel. Confirm that the component meets RoHS compliance standards and is lead-free. Ensure the procurement specification matches the required 3.3 V supply voltage and LVPECL interface requirements for the target application.

Programmable Timers And Oscillators Selection Notes

Select this oscillator when a differential LVPECL output is required for high-speed digital interfaces. Consider the 50.00 MHz frequency and ±50 PPM stability against system timing budgets. Evaluate the 6-pin CLCC package dimensions (7x5 mm) for PCB layout constraints. Verify that the 3.3 V power supply aligns with the system's available voltage rails.

Programmable Timers And Oscillators Part Context

This component belongs to onsemi’s PureEdge/C0116 clock family, which focuses on providing accurate and precision clock solutions. The NBXHGA053 variant specifically targets applications needing low jitter performance at 50 MHz. It is part of a broader portfolio of crystal oscillators designed to replace discrete timing components with integrated PLL-based solutions.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements must match the 50.00 MHz frequency, LVPECL output type, and 6-pin CLCC package. Verify compatibility with existing termination networks (50 Ω to VTT = VDD - 2.0 V). Check if alternative suppliers offer equivalent phase noise and jitter specifications within the same thermal and voltage constraints.

Programmable Timers And Oscillators FAQ

How does the OE pin function?

The OE pin is an LVTTL/LVCMOS control input. When left floating or held HIGH, the output is active. When driven LOW, the outputs enter a high-impedance state.

What is the recommended output termination?

Outputs should be terminated with 50 Ω receiver termination resistors connected to VTT, where VTT equals VDD minus 2.0 V.

What is the start-up time for the oscillator?

The maximum start-up time for the device is 5 ms.
