8761CYILF - Renesas Electronics

Description: The 8761I is a low voltage, low skew PCI / PCI-X clock generator. The 8761I has a selectable REF_CLK or crystal input. The REF_CLK input accepts LVCMOS or LVTTL input levels. The 8761I has a fully integrated PLL along with frequency configurable clock and feedback outputs for multiplying and regenerating clocks with "zero delay". Using a 20MHz or 25MHz crystal or a 33.333MHz or 66.666MHz reference frequency, the 8761I will generate output frequencies of 33.333MHz, 66.666MHz, 100MHz and 133.333MHz simultaneo

8761CYILF Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (APL-AN-1201) which includes thermal design considerations, such as thermal vias, copper pours, and component placement.
  • Renesas recommends using an external overcurrent protection circuit, such as a current sense resistor and a comparator, to detect overcurrent conditions and trigger a shutdown or warning signal.
  • While the datasheet specifies an operating temperature range of -40°C to 125°C, Renesas recommends derating the device's performance at high temperatures (above 100°C) to ensure reliable operation.
  • Yes, the 8761CYILF is designed to withstand vibrations up to 10G (rms) in the frequency range of 10Hz to 2kHz, but Renesas recommends following their guidelines for vibration testing and ensuring proper PCB mounting and component selection.
  • Renesas provides a troubleshooting guide in their application note (APL-AN-1202) which includes steps to verify the oscillator's operation, check for clock signal integrity, and diagnose common issues.
