Overview
The NSC5263B-10M is a 10 MHz Oven-Controlled Crystal Oscillator (OCXO) manufactured by NDK. It utilizes CMOS technology to deliver a square wave output signal at a supply voltage of 3.3V. The component is housed in a 10-SMD, leadless package designed for surface-mount installation. This oscillator provides high frequency stability characteristic of oven-controlled designs, suitable for applications requiring precise timing references.
Feature Summary
- Oven-controlled crystal oscillator architecture ensures high frequency stability
- CMOS output interface generates square wave signals
- Operates with a 3.3V power supply
- Surface-mount 10-SMD leadless package design
Applications
- Precision timing reference systems
- Telecommunications equipment requiring stable clock sources
- Test and measurement instrumentation
- Data communication interfaces
Procurement Notes
Verify the specific output load requirements and supply voltage tolerance against the official datasheet before integration. Confirm that the 10-SMD footprint matches the target PCB layout dimensions. Ensure thermal management strategies account for the internal oven heating element inherent to OCXO operation. Cross-reference the manufacturer part number NSC5263B-10M with authorized distributors to ensure authenticity and traceability.
Selection Notes
Select this component when superior frequency stability over temperature variations is required compared to standard TCXOs or HCSPs. The CMOS output simplifies interfacing with digital logic circuits operating at 3.3V. Consider the higher power consumption typical of oven-controlled designs versus non-oven types. Evaluate the physical size constraints of the 10-SMD package against available board space.
Part Context
This model belongs to the NSC5263B series of OCXOs from NDK. It is distinct from the NX3225SA and NX2520SA crystal families also listed in the provided data, which are passive resonators rather than active oscillators. The NSC5263B-10M represents a complete timing solution with integrated control circuitry.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's product configuration guide for potential alternative models within the NSC5263B series or other NDK OCXO lines.
