Description:The MK5811C device generates a low EMI output clock from a clock or crystal input. The device is designed to dither a high emissions clock to lower EMI in consumer applications. Using IDT's proprietary mix of analog and digital Phase Locked Loop (PLL) technology, the device spreads the frequency spectrum of the output and reduces the frequency amplitude peaks by several dB. The MK5811C offers both centered and down spread from a high-speed clock input. For different multiplier configurations, use the MK581
Renesas provides a recommended PCB layout guide in their application note (AN1818) for the MK5811CMILF, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
To ensure reliable operation in high-temperature environments, it's essential to follow the recommended operating conditions, use a suitable thermal interface material, and implement a robust thermal management system. Additionally, consider using a thermistor or temperature sensor to monitor the device temperature and implement thermal shutdown or warning mechanisms if necessary.
Using a different capacitor value for the VCC bypass capacitor may affect the device's power supply noise rejection and stability. Renesas recommends using a 10uF capacitor as specified in the datasheet, but if a different value is used, it's essential to ensure the capacitor meets the recommended specifications and to verify the device's performance through simulation and testing.
While the MK5811CMILF is designed for military applications, it can be used in non-military applications that require high-reliability and ruggedness. However, it's essential to ensure that the device meets the specific requirements of the application, and to consult with Renesas or a qualified distributor for availability and support.
Renesas recommends following the JEDEC J-STD-020D.1 standard for soldering the MK5811CMILF. This standard provides guidelines for temperature, time, and soldering techniques to ensure reliable connections and minimize the risk of damage to the device.
