Description:The 854104I is a low skew, high performance 1-to-4 Differential-to-LVDS Clock Fanout Buffer. Utilizing Low Voltage Differential Signaling (LVDS), the 854104I provides a low power, low noise, solution for distributing clock signals over controlled impedances of 100?. The 854104I accepts a differential input level and translates it to LVDS output levels. Guaranteed output and part-to-part skew characteristics make the 854104I ideal for those applications demanding well defined performance and repeatability.
Renesas provides a recommended PCB layout guide for the 854104AGILFT, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance. Contact Renesas support for more information.
Renesas recommends following the power sequencing guidelines outlined in the datasheet, which involves powering up the VCC and VDD pins in a specific order to prevent damage to the device. Additionally, Renesas provides a power sequencing application note that provides more detailed guidance.
While the datasheet specifies an operating temperature range of -40°C to 125°C, Renesas recommends derating the device's performance at temperatures above 105°C to ensure reliability and prevent thermal shutdown.
The 854104AGILFT is not specifically designed for radiation-hardened applications. However, Renesas offers radiation-hardened versions of similar devices, such as the RL78/G14, which are designed for use in high-reliability applications.
Renesas recommends following the ESD protection guidelines outlined in the datasheet, which include using ESD protection devices, such as TVS diodes, and following proper handling and storage procedures to prevent ESD damage.
