NBXSBA008LNHTAG

Programmable Timers And Oscillators Overview

The NBXSBA008LNHTAG is a single-frequency crystal oscillator from onsemi's PureEdge family, generating a fixed 161.1328 MHz LVPECL differential clock signal. It utilizes a high-Q fundamental mode crystal and a Phase Lock Loop (PLL) multiplier to achieve ultra-low jitter and phase noise performance. The device operates on a 3.3 V power supply with a ±10% tolerance range and provides an LVTTL/LVCMOS compatible output enable pin for tri-state control. Packaged in a hermetically sealed 6-pin ceramic CLCC (7x5 mm) surface-mount format, it supports an operating temperature range of -40°C to +85°C.

Programmable Timers And Oscillators Procurement Notes

Verify that the specific ordering suffix LNHTAG corresponds to the 100-unit tape and reel packaging configuration as defined in the official datasheet. Confirm that the component meets RoHS compliance standards and is lead-free. Ensure the procurement specification matches the required hermetically sealed ceramic package type rather than standard plastic packages.

Programmable Timers And Oscillators Selection Notes

Select this component when a fixed 161.1328 MHz frequency is required for LVPECL logic interfaces. The device is suitable for designs needing low phase noise and strict frequency stability of ±50 ppm over the industrial temperature range. Verify that the system can provide the necessary VTT termination voltage, typically set at VDD minus 2.0 V, for proper driver loading.

Programmable Timers And Oscillators Part Context

This part belongs to the NBXSBA008 series within onsemi's PureEdge/C0116 clock family. It is specifically engineered to meet modern requirements for 3.3 V LVPECL clock generation. The device integrates a high-Q fundamental crystal directly with the PLL circuitry to ensure precision timing solutions for sensitive digital systems.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements must match the 161.1328 MHz frequency, LVPECL output type, and 6-pin CLCC package dimensions. Verify compatibility with the ±50 ppm total frequency stability requirement and the 3.3 V operating voltage range before substitution.

Programmable Timers And Oscillators FAQ

What is the typical RMS phase jitter specification for this oscillator?

The typical RMS phase jitter is 0.4 ps, measured within the 12 kHz to 20 MHz offset frequency range from the carrier.

How is the output enabled or disabled?

The Output Enable (OE) pin controls the state; applying a HIGH level activates the output, while a LOW level places the outputs in a high-impedance state. Leaving the pin floating defaults to the active HIGH state.

What is the recommended termination for the LVPECL outputs?

The outputs should be terminated with 50 Ω receiver termination resistors connected to a VTT voltage, which is typically calculated as VDD minus 2.0 V.
