871S1022EKLF - Renesas Electronics

Description: IDT's PLL-based clock generators offer sub-picosecond jitter, low-skew clock outputs, and edge rates that meet the ever-growing demands of today's networking solutions. The 871S1022 is a PLL-based clock generator specifically designed for PCI Express® Clock Generation applications. The device generates 100MHz, 125MHz, 250MHz or 500MHz from either a 25MHz fundamental mode crystal or a 100MHz recovered clock. The 871S1022 has two modes of operation: (1) high frequency jitter attenuator and (2) high performanc

871S1022EKLF Frequently Asked Questions (FAQs)

  • A multi-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a minimum of 1mm clearance around the package for heat dissipation. A thermal pad on the bottom of the package should be connected to a thermal plane or a heat sink.
  • Use a shielded enclosure, keep signal lines short, and use a common mode choke or ferrite bead on the power lines. Ensure a solid ground plane and decouple power supplies. Follow the recommended layout guidelines in the datasheet.
  • The input capacitor should be a low-ESR ceramic capacitor (e.g., X5R or X7R) with a value between 4.7uF to 10uF. The output capacitor should be a low-ESR electrolytic capacitor with a value between 10uF to 22uF. Select capacitors with a voltage rating at least 1.5 times the maximum input voltage.
  • Use a current sense resistor and a comparator to monitor the current. Implement a foldback current limiting scheme to prevent damage during overcurrent conditions. Add a thermal shutdown circuit to protect the device from overheating.
  • Use a digital multimeter to measure voltage and current. Verify the output voltage ripple and noise using an oscilloscope. Perform a load transient response test to ensure the device can handle sudden changes in load current.
