SX3DF156.250B20F30DNN 156.25MHz LVPECL,LVDS ,HCSL 6-SMD Differential Crystal Oscillator

SX3DF156.250B20F30DNN is a high-performance 156.25MHz Differential Crystal Oscillator manufactured by SCTF. This sophisticated passive component is designed to generate a precise and stable clock signal, crucial for high-speed digital systems. Unlike standard single-ended oscillators, differential crystal oscillators produce two output signals that are 180 degrees out of phase, offering superior noise immunity and reduced electromagnetic interference (EMI). This makes them indispensable in applications demanding signal integrity and reliable timing. The SX3DF156.250B20F30DNN supports multiple output types including LVPECL, LVDS, and HCSL, providing exceptional versatility for various interface requirements in advanced electronic designs.

Key Specifications

The SX3DF156.250B20F30DNN boasts a comprehensive set of specifications tailored for demanding applications:

• Output: LVPECL, LVDS, HCSL – This critical attribute signifies the oscillator’s ability to interface with three widely used high-speed differential signaling standards. LVPECL (Low Voltage Positive Emitter Coupled Logic) offers high speed and low noise, often used in telecom and networking. LVDS (Low Voltage Differential Signaling) is known for its low power consumption and high noise immunity over long distances. HCSL (High-Current Source Logic) is commonly found in PCI Express and other high-speed serial data links. The multi-output capability ensures broad compatibility and design flexibility.
• Series: 3Z – This designates the product series from SCTF, often indicating a specific family of components with shared characteristics or performance tiers. Understanding the series helps in identifying compatible or related parts within the manufacturer’s portfolio.
• Frequency: 156.25MHz – This is the fundamental operating frequency of the oscillator, providing the precise clock signal at 156.25 million cycles per second. This specific frequency is commonly used in various communication and data processing systems.
• Size (mm): 3.2×2.5×0.90 – This compact dimension indicates a small footprint, making it suitable for space-constrained applications. The surface mount design further contributes to miniaturization and automated assembly processes.
• Phase Jitter: 0.5pS – Phase jitter is a measure of the short-term variations in the period of a clock signal. A very low phase jitter of 0.5 picoseconds (pS) is excellent, signifying a highly stable and clean clock signal, which is crucial for high-speed data transmission and reducing bit error rates in sensitive digital systems.
• Mounting Type: Surface Mount – This specifies that the component is designed for surface mount technology (SMT), allowing for automated placement and soldering on printed circuit boards (PCBs), leading to higher manufacturing efficiency and component density.
• Component Type: Differential Crystal Oscillator – This clearly identifies the device as a crystal oscillator that produces differential output signals, emphasizing its benefits in noise reduction and signal integrity over single-ended alternatives.
• Package / Case: 6-SMD – This refers to the physical package style, a 6-pin Surface Mount Device. This standard packaging facilitates easy integration into modern PCB designs.
• Supply Voltage: 1.8V, 2.5V, 3.3V – The ability to operate across multiple standard supply voltages (1.8V, 2.5V, 3.3V) offers significant flexibility for designers, allowing integration into various system architectures without requiring additional voltage conversion circuitry.
• Frequency Range: 90 – 200MHz – While this specific part operates at 156.25MHz, the frequency range indicates the broader family of oscillators within the 3Z series, suggesting that other frequencies within this range might be available with similar characteristics.
• Frequency Stability: ±50ppm – Frequency stability measures how much the output frequency can deviate from its nominal value over temperature, voltage, and aging. A stability of ±50 parts per million (ppm) indicates a reliable and consistent clock source under varying environmental conditions.
• Frequency Tolerance: ±20ppm – Frequency tolerance specifies the maximum initial deviation of the output frequency from its nominal value at room temperature. A tolerance of ±20ppm ensures that the oscillator starts up very close to its intended frequency.
• Operating Temperature: -40℃ to +85℃ – This wide operating temperature range signifies the component’s robustness and suitability for industrial and automotive applications, where extreme temperatures are common.

Features and Benefits

• Versatile Output Options: Supports LVPECL, LVDS, and HCSL outputs, providing unparalleled flexibility for integration into diverse high-speed digital systems, reducing the need for multiple component variants.
• Superior Signal Integrity: Differential output signals inherently offer excellent common-mode noise rejection and reduced EMI, leading to cleaner clock signals and lower bit error rates in critical applications.
• Ultra-Low Phase Jitter: With a phase jitter of just 0.5pS, the SX3DF156.250B20F30DNN ensures highly precise timing, essential for high-speed data communication and synchronization in complex digital circuits.
• Wide Operating Temperature Range: Capable of operating from -40℃ to +85℃, making it suitable for robust industrial, telecommunications, and automotive environments where temperature extremes are common.
• Compact and Power Efficient: The 3.2×2.5×0.90mm 6-SMD package and multi-voltage supply options (1.8V, 2.5V, 3.3V) contribute to space-saving designs and optimized power consumption.

Typical Applications

• Telecommunications Infrastructure: Essential for clocking high-speed data converters, network processors, and optical transceivers in base stations, routers, and switches, where precise timing and low jitter are paramount for reliable data transmission.
• Data Centers and Servers: Used in server motherboards, storage area networks (SANs), and high-performance computing (HPC) systems to provide stable clock signals for CPUs, FPGAs, and high-speed interconnects like PCIe and Ethernet.
• Industrial Automation and Control: Critical for synchronizing real-time control systems, industrial Ethernet, and vision systems, ensuring precise operation and data integrity in harsh industrial environments.
• Test and Measurement Equipment: Provides accurate reference clocks for oscilloscopes, spectrum analyzers, and signal generators, where the integrity and stability of the clock directly impact measurement precision.
• Medical Imaging Systems: Utilized in MRI, CT scanners, and ultrasound equipment for clocking high-resolution data acquisition and processing units, where signal purity and reliability are vital for diagnostic accuracy.
