DS90LV031BTM Parameter Table

Instructions for DS90LV031BTM

1. Supply Voltage (VCC):

   • Ensure the supply voltage is within the range of 1.5V to 3.6V.
   • Use a stable power source to avoid voltage fluctuations that could affect performance.

2. Differential Output Voltage (VOD):

   • The differential output voltage should be between 275mV and 375mV for optimal performance.
   • Use a 100Ω termination resistor to match the characteristic impedance of the transmission line.

3. Common-Mode Output Voltage (VOCM):

   • The common-mode output voltage should be between 0.9V and 1.5V.
   • This voltage is typically set by the power supply and the internal circuitry of the device.

4. Output Rise and Fall Time (tr, tf):

   • The rise and fall times should be between 1.0ns and 2.0ns.
   • Ensure that the load capacitance (CL) and load resistance (RL) are within the specified ranges to achieve these timings.

5. Input Voltage Levels (VIH, VIL):

   • The input high voltage (VIH) should be at least 1.4V.
   • The input low voltage (VIL) should be no more than 0.8V.
   • These levels ensure proper logic level recognition.

6. Input Leakage Current (IIL):

   • The input leakage current should be within ±1μA to prevent excessive power consumption or signal degradation.

7. Operating and Storage Temperature:

   • The operating temperature range is from -40°C to 85°C.
   • The storage temperature range is from -65°C to 150°C.
   • Ensure the device is stored and operated within these temperature limits to avoid damage.

8. Power Consumption:

   • In active mode, the power consumption is typically 20mW.
   • In shutdown mode, the power consumption is typically 1μW.
   • Use the shutdown feature to reduce power consumption when the device is not in use.

9. Layout and PCB Design:

   • Use short, controlled impedance traces for differential pairs to minimize signal degradation.
   • Place decoupling capacitors close to the power pins to filter out noise and provide stable power.

10. Handling and ESD Protection:

    • Handle the device with care to avoid static discharge.
    • Use ESD protection measures such as wrist straps and grounded work surfaces.

By following these parameters and instructions, you can ensure reliable and efficient operation of the DS90LV031BTM in your design.
