Instructions for DS96173CN:

  1. Power Supply:

    • Ensure the supply voltage (VCC) is within the specified range of 2.25V to 5.5V.
    • Use a stable power source to avoid fluctuations that could affect performance.
  2. Temperature Considerations:

    • Operate the device within the temperature range of -40°C to 85°C to ensure reliable performance.
    • Avoid exposing the device to extreme temperatures outside this range.
  3. Data Transmission:

    • The DS96173CN supports a maximum data rate of 100 Mbps.
    • Ensure that the data signals are within the differential input voltage threshold of 100 to 200 mV.
  4. Differential Signaling:

    • The differential output voltage (VOD) should be maintained between 400 mV and 600 mV for optimal performance.
    • The differential input voltage (VID) should be within the range of 100 mV to 200 mV to ensure proper signal detection.
  5. Current Consumption:

    • The quiescent input current (IIK) and output current (IOK) per channel are typically around 1 mA.
    • Design the circuit to handle these current levels to avoid overheating or power supply issues.
  6. Timing Parameters:

    • The propagation delay (tPLH, tPHL) is typically 15 ns, which should be considered when designing timing-critical applications.
    • The maximum skew (tSKEW) between differential pairs is 1 ns, ensuring minimal signal distortion.
  7. Power Management:

    • The maximum power dissipation (PD) is 100 mW. Ensure adequate heat dissipation to prevent overheating, especially in high-density designs.
  8. Layout and PCB Design:

    • Use controlled impedance traces for differential pairs to maintain signal integrity.
    • Keep the layout compact and minimize trace lengths to reduce parasitic capacitance and inductance.
  9. Testing and Validation:

    • Test the device under various operating conditions to ensure it meets the specified parameters.
    • Validate the design with appropriate test equipment to confirm performance and reliability.
