UCC5640PW28概述

    Product Introduction: UCC5640 Active Terminator
    The UCC5640 is an advanced electronic component specifically designed as an active terminator for low voltage differential (LVD) SCSI networks. It caters to the growing demand for high-speed communication in data transfer applications. The UCC5640's architecture ensures superior performance in LVD-only systems while reducing system costs. It plays a crucial role in enhancing frequency response on the LVD bus, making it ideal for environments where fast and reliable data transmission is essential.
    Applications:
    - SCSI SPI-2 (Fast-40)
    - SCSI SPI-3 (Fast-80 and Fast-160)
    - SCSI SPI-4 (Ultra320)
    - Server and storage subsystems
    - High-performance computing
    Technical Parameters
    Below are the key technical specifications extracted from the UCC5640 datasheet:
    | Parameter | Value | Unit |
    |
    | Operating Voltage Range | 2.7 to 5.25 | V |
    | Dissolve-to-Threshold Voltage | 56 mV
    | Regulated Output Voltage (1.25V) | ±80 mV | V |
    | Regulated Output Voltage (1.3V) | ±100 mV | V |
    | Differential Impedance | 100 to 110 | Ω |
    | Common Mode Impedance | 110 to 165 | Ω |
    | Current Consumption (Disabled Mode) | ≤400 | µA |
    | Maximum Power Dissipation | 1 | W |
    Product Features and Advantages
    The UCC5640 stands out with its unique features, offering a competitive edge in modern SCSI-based systems:
    1. Industry-First Design: As the first LVD-only active terminator, it meets SCSI SPI-2, SPI-3, and SPI-4 standards.
    2. Wide Operating Voltage Range: The ability to operate from 2.7 V to 5.25 V provides flexibility across various power domains.
    3. Differential Fail-Safe Bias: Prevents signal degradation by maintaining precise impedance even under failure conditions.
    4. High-Impedance Receiver: Operates effectively even when powered off or in disabled modes.
    5. Compact Form Factor: Available in 24-pin and 28-pin TSSOP packages for efficient PCB layout.
    Its ability to comply with evolving SCSI standards makes it a future-proof solution for migrating to higher-speed systems.
    Application Case Studies and Recommendations
    Example 1: High-Speed SCSI Network
    The UCC5640 is commonly deployed in high-speed storage systems where differential signaling enhances signal integrity over longer cable lengths. To optimize performance:
    - Ensure proper filtering on the DIFFB line with a 50-kΩ resistor and a 4.7-µF capacitor.
    - Use balanced differential pairs to minimize crosstalk and maximize signal quality.
    Example 2: Cost-Efficient Design
    For cost-sensitive applications, users can leverage the UCC5640’s low-voltage differential termination capability while achieving optimal bus performance. Consider the following recommendations:
    - Implement decoupling capacitors close to the TRMPWR and REG pins to stabilize the power supply.
    - Avoid connecting multiple DIFSENS outputs at the same end of the bus to maintain signal integrity.
    Compatibility and Support
    The UCC5640 is designed for seamless integration into existing SCSI systems and exhibits excellent compatibility with:
    - 3.3V or 5V Systems: Suitable for both low-voltage and standard voltage systems.
    - SPI Standards: Fully compliant with SCSI SPI-2, SPI-3, and SPI-4 standards.
    Texas Instruments offers robust support via its extensive documentation, customer forums, and comprehensive application notes. Additionally, engineers can access detailed packaging and ordering information directly from TI's website.
