Description:The 180-51 generates a low EMI output clock from a clock or crystal input. The device uses IDT's proprietary mix of analog and digital Phase-Locked Loop (PLL) technology to spread the frequency spectrum of the output, thereby reducing the frequency amplitude peaks by several dB. The 180-51 offers center spread selection of +/-0.625% and +/-1.875%. Refer to the MK1714-01/02 for the widest selection of input frequencies and multipliers. IDT offers a complete line of EMI reducing clock generators. Consult us w
Renesas provides a recommended PCB layout guide in their application note (AP61101) for the 180M-51LFT, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
Renesas recommends using an external overcurrent protection circuit, such as a fuse or a dedicated overcurrent protection IC, to protect the 180M-51LFT from excessive current. The datasheet provides guidelines for selecting the appropriate overcurrent protection component.
While the datasheet specifies an operating temperature range of -40°C to 125°C, Renesas recommends derating the device's performance at temperatures above 85°C to ensure reliable operation. Consult the datasheet and application notes for specific derating guidelines.
Renesas provides EMC guidelines in their application note (AP61102) for the 180M-51LFT, which includes recommendations for PCB layout, component selection, and shielding to minimize electromagnetic interference (EMI) and ensure compliance with relevant EMC standards.
Renesas recommends storing the 180M-51LFT in a dry, cool place (less than 30°C and 60% relative humidity) to prevent moisture absorption and damage. Avoid exposing the device to direct sunlight, high temperatures, or high humidity during storage.
