NBXSBA023LN1TAG

Programmable Timers And Oscillators Overview

The NBXSBA023LN1TAG is a single frequency crystal oscillator (XO) from the 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 400 MHz output with ultra-low jitter and phase noise. The device features hermetically sealed ceramic SMD packaging in a 5 mm x 7 mm CLCC-6 package. Key electrical specifications include a power supply current of 85 mA typical at 3.3 V ±10%, an operating temperature range of -40°C to +85°C, and a total frequency stability of ±50 PPM.

Programmable Timers And Oscillators Feature Summary

• LVPECL differential output with ultra-low jitter (0.5 ps RMS, 12 kHz–20 MHz) and phase noise performance.
• Hermetically sealed ceramic SMD package (CLCC-6) compliant with MIL-STD-833 mechanical standards.
• Built-in Output Enable (OE) pin supporting LVTTL/LVCMOS logic levels for tri-state control.
• Frequency stability of ±50 PPM over the full operating temperature range.

Programmable Timers And Oscillators Applications

• Networking equipment
• SPI-4 interface systems

Programmable Timers And Oscillators Procurement Notes

Verify that the specific ordering suffix LN1TAG corresponds to the tape and reel shipping configuration containing 1,000 units per reel. Confirm the part number matches the ±50 PPM frequency stability variant designated by the 'A' suffix in the base model NBXSBA023. Ensure compatibility with the specified 3.3 V ±10% power supply requirements during procurement planning.

Programmable Timers And Oscillators Selection Notes

Select this component when a 400 MHz LVPECL clock signal with low jitter is required for networking or SPI-4 applications. Choose the NBXSBA023 variant specifically for ±50 PPM stability; use NBXSBB023 if ±20 PPM stability is needed. Ensure the design accommodates the 85 mA typical supply current and provides proper 50 Ω termination resistors to VTT = VDD - 2 V for the differential outputs.

Programmable Timers And Oscillators Part Context

This oscillator belongs to ON Semiconductor’s PureEdge/C0116 clock family, which provides precision clock solutions. It is functionally similar to the NBXSBB023 but differs in frequency stability specifications. The device is packaged in a 6-pin CLCC case (CASE 848AB) and is available in lead-free (Pb-Free) configurations.

Programmable Timers And Oscillators Replacement Considerations

The NBXSBB023LN1TAG serves as a direct functional substitute within the same package and voltage domain, offering improved frequency stability of ±20 PPM compared to the ±50 PPM of the NBXSBA023. No other cross-model replacements are documented in the provided datasheet.

Programmable Timers And Oscillators FAQ

How does the Output Enable (OE) pin function?

The OE pin accepts LVTTL/LVCMOS logic levels. When left floating, it defaults to a logic HIGH state, keeping the output active. A logic LOW level places the output pins into a high-impedance (High Z) state.

What is the recommended output termination for the LVPECL signals?

The non-inverted (CLK) and inverted (CLK) outputs should typically be loaded with 50 Ω receiver termination resistors connected to VTT, where VTT is defined as VDD minus 2 V.

What is the start-up time for the oscillator?

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