NBVSPA042LN1TAG

Programmable Timers And Oscillators Overview

The NBVSPA042LN1TAG is a voltage-controlled crystal oscillator (VCXO) from the PureEdge/C0116 series, manufactured by onsemi. It operates at a fixed output frequency of 74.25 MHz with a pullable range of ±100 ppm and frequency stability of ±50 ppm. The device utilizes a high Q fundamental mode crystal and PLL multiplier to generate an ultra-low jitter LVDS differential output. Key electrical parameters include a power supply current of 75 mA typical, operating voltage of 3.3 V ±10%, and RMS phase jitter of 0.9 ps (12 kHz to 20 MHz). It is housed in a hermetically sealed 6-pin CLCC package (Case 848AB, 7x5 mm) and supports an operating temperature range of -40°C to +85°C.

Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'LN1' corresponds to the 7x5 mm CLCC package (Case 848AB) as listed in the datasheet ordering table. Confirm that the 'G' suffix for Pb-Free compliance is included in the full part number if required by assembly specifications. Check tape and reel packaging quantities of 1,000 units per the standard shipping configuration.

Programmable Timers And Oscillators Selection Notes

Select this component when a precise 74.25 MHz clock signal with low phase noise is required for networking or SONET applications. Ensure the design accommodates the 3.3 V power supply and LVDS termination requirements (100 Ω across differential pair). Verify that the ±100 ppm pull range meets system tuning needs and that the hermetic package is suitable for the environmental conditions.

Programmable Timers And Oscillators Part Context

This device belongs to the NBVSPA015 Series (PureEdge/C0116), which provides precision clock generation solutions using silicon-based technology. The series includes various factory-configurable frequencies ranging from 60 MHz to 700 MHz, all sharing similar electrical characteristics and package options such as the 5x7 mm and 3.2x5 mm CLCC formats.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same series include other NBVSPA0xx variants with different factory-set frequencies but identical pinouts and packages, such as NBVSPA017LN1TAG (156.25 MHz) or NBVSPA018LN1TAG (155.52 MHz). Cross-series substitution requires verification of frequency, jitter, and package compatibility.
