NBXDDA016LN1TAG

Programmable Timers And Oscillators Overview

The NBXDDA016LN1TAG is a dual frequency CML clock oscillator from onsemi’s PureEdge/C0116 family. It provides selectable output frequencies of 133.33 MHz or 137.93 MHz using a high Q fundamental crystal and PLL multiplier. The device features ultra-low jitter (0.4 ps RMS, 12 kHz–20 MHz) and phase noise performance in a hermetically sealed ceramic SMD package. Operating at 3.3 V ±10%, it delivers differential CML outputs with an LVTTL/LVCMOS control interface for enable and frequency selection.

Programmable Timers And Oscillators Feature Summary

• Dual Frequency Selection: Outputs 133.33 MHz (default) or 137.93 MHz via FSEL pin
• Ultra-Low Jitter: 0.4 ps RMS phase jitter (12 kHz to 20 MHz)
• Hermetic Packaging: 6-pin CLCC (CASE 848AB) SMD package
• Differential Output: CML drivers with 50 Ω termination to VDD

Programmable Timers And Oscillators Applications

• High-End Servers
• Basestation Clock Generation
• General Purpose Clock Margining

Programmable Timers And Oscillators Procurement Notes

Verify the LN1TAG suffix indicates a 1000-unit tape and reel quantity. Confirm the 'A' designation corresponds to ±50 PPM total frequency stability. Ensure the application supports 3.3 V logic levels for OE and FSEL inputs. Check for RoHS compliance requirements matching the Pb-Free package marking.

Programmable Timers And Oscillators Selection Notes

Select NBXDDA016LN1TAG for applications requiring ±50 PPM stability. Use NBXDDB016LN1TAG if ±20 PPM stability is required. Ensure the load circuit uses 50 Ω resistors to VDD for proper CML termination. Verify that the operating temperature range of -40°C to +85°C meets system thermal constraints.

Programmable Timers And Oscillators Part Context

This component belongs to the PureEdge/C0116 clock family. It shares the same package and basic functionality as the NBXDDB016 variant, differing primarily in frequency stability specifications. The device integrates a PLL multiplier and fundamental mode crystal within a single hermetic package.

Programmable Timers And Oscillators Replacement Considerations

NBXDDB016LN1TAG offers identical electrical characteristics except for tighter frequency stability (±20 PPM vs ±50 PPM). No other direct substitutes are documented in the provided datasheet.
