Description:The 841604I-01 is an optimized PCIe and sRIO clock generator. 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 841604I-01 can also drive the high-speed sRIO and PCIe SerDes clock inp
Renesas provides a recommended PCB layout guide in their application note (APN) documents, which can be found on their website. The guide includes thermal vias, copper pours, and other layout considerations to ensure optimal thermal performance.
Renesas recommends following the power sequencing guidelines outlined in the datasheet, which involves powering up the VCC and VCCIO pins in a specific order. Additionally, Renesas provides a power sequencing application note that provides more detailed information and examples.
Renesas recommends using high-quality, low-ESR decoupling capacitors with a value of 0.1uF to 1uF, placed as close as possible to the power pins. The datasheet provides more detailed information on decoupling capacitor selection and placement.
Renesas recommends following standard ESD protection guidelines, including using ESD-sensitive handling procedures, using ESD-protective packaging, and incorporating ESD protection devices (such as TVS diodes) into the PCB design.
Renesas provides thermal design guidelines in their datasheet and application notes, which include recommendations for thermal vias, heat sinks, and airflow. Engineers should also consider the device's thermal resistance, junction temperature, and power dissipation when designing their system.
