841654AGILF - Renesas Electronics

Description: The 841654I is an optimized PCIe and sRIO clock generator and member of the family of high-performance clock solutions from IDT. The device uses a 25MHz parallel crystal to generate 100MHz and 125MHz clock signals, replacing solutions requiring multiple oscillator and fanout buffer solutions. The device has excellent phase jitter (< 1ps rms) suitable to clock components requiring precise and low-jitter PCIe or sRIO or both clock signals. Designed for telecom, networking and industrial applications, the 8416

841654AGILF Frequently Asked Questions (FAQs)

  • Renesas recommends a 4-layer PCB with a solid ground plane and thermal vias to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended for the power plane.
  • Implement a robust communication protocol with error detection and correction mechanisms, such as CRC and checksums. Ensure proper signal termination, and use a common clock source to synchronize devices on the bus.
  • Power up the device in the following sequence: VCC, AVCC, and then DVCC. Ensure a minimum of 10 ms delay between each power-up step to prevent latch-up.
  • Use a metal shield or a Faraday cage to enclose the device, and ensure proper grounding and decoupling of power supplies. Implement EMI filters and shielding on I/O lines to minimize radiation.
  • Ensure a minimum of 10 mm clearance around the device for airflow, and use a heat sink with a thermal interface material (TIM) to dissipate heat. Avoid blocking airflow vents and ensure good thermal conductivity between the device and heat sink.
