PE19XR1003

Overview

The PE19XR1003 is a free-running reference oscillator manufactured by Pasternack, designed for applications requiring stable frequency generation. It operates at a fundamental frequency of 10 MHz and utilizes an internal reference source. The device features low phase noise performance, specified at -150 dBc/Hz, ensuring signal integrity in sensitive RF environments. It is equipped with an SMA output connector for direct integration into test and measurement systems or communication equipment.

Feature Summary

• Generates a stable 10 MHz output frequency using an internal reference mechanism.
• Delivers low phase noise characteristics to maintain high signal purity.
• Provides a standard SMA interface for straightforward system connectivity.

Applications

• Test and measurement instrumentation
• Communication system timing references
• Signal generator synchronization

Procurement Notes

Verify the specific datasheet version provided by Pasternack or authorized distributors to confirm current manufacturing status and compliance details. Ensure that the SMA connector type matches the receiving equipment interface requirements. Cross-reference the phase noise specification against application tolerances before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 10 MHz reference is required without external modulation inputs. The internal reference design simplifies circuit layout compared to voltage-controlled alternatives. Evaluate the -150 dBc/Hz phase noise metric against system sensitivity requirements to ensure adequate signal-to-noise ratio for the intended operational environment.

Part Context

This part belongs to Pasternack's family of specialty oscillators and synthesizers. It serves as a foundational timing source within broader RF subsystems. Unlike programmable synthesizers, it provides a single, fixed frequency output, making it suitable for dedicated reference roles rather than frequency-agile applications.

Replacement Considerations

No public substitute part numbers are documented for this specific model. Direct replacement requires matching the 10 MHz frequency, SMA interface, and phase noise specifications. Consult Pasternack technical support for potential legacy replacements if discontinuation occurs.
