PE43670A-Z Frequently Asked Questions (FAQs)

  • pSemi recommends a 4-layer PCB with a solid ground plane, and thermal vias under the device to dissipate heat. A thermal pad on the bottom of the device should be connected to a thermal plane on the PCB. Refer to the pSemi application note for detailed layout guidelines.
  • The PE43670A-Z requires a bias voltage of 3.3V ± 10% on the VDD pin, and a bias current of 10mA ± 10% on the VBIAS pin. Ensure that the bias voltage and current are stable and within the recommended range for optimal performance.
  • The PE43670A-Z has a differential input impedance of 100 ohms and a differential output impedance of 50 ohms. Ensure that the input and output signals are impedance-matched to these values for optimal performance and to minimize signal reflections.
  • The PE43670A-Z requires a specific power-on and power-off sequencing to prevent damage to the device. Ensure that the VDD pin is powered on before the VBIAS pin, and that the VBIAS pin is powered off before the VDD pin.
  • The PE43670A-Z operates over a temperature range of -40°C to +85°C. The device's performance may degrade at higher temperatures, so ensure that the device is operated within the recommended temperature range for optimal performance.
