Additional Details

The ICS85310AYI21LN operates on a 3.3V power supply and is designed to interface with LVCMOS/LVTTL logic levels. The low additive jitter ensures that the output clocks maintain the integrity of the input clock signal, which is essential for high-speed data transmission and processing applications. The device's fanout capability allows a single clock source to drive multiple loads without significant signal degradation. The specified operating temperature range makes it suitable for use in industrial and harsh environments. Proper termination techniques are recommended to minimize signal reflections and ensure optimal signal integrity. The device's LQFP package facilitates easy integration into a variety of PCB designs.
