Instructions for DS96173CN:
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.
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.
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.
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.
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.
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.
Power Management:
- The maximum power dissipation (PD) is 100 mW. Ensure adequate heat dissipation to prevent overheating, especially in high-density designs.
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.
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.
