The IDT49FCT3805SO device is a high-speed integrated circuit manufactured by Integrated Device Technology (IDT). It is a Clock/Timing - Clock Buffers, Drivers product. This device is an octal low-skew differential crystal/clock driver. It is designed to provide the lowest possible signal skew between multiple outputs. It provides a low skew (p-p) output signal of 5ns over the 3V to 3.6V voltage range. Its maximum output signal swing is 2.5V.

This device offers several application fields, one of which is driving differential clock signals to multiple outputs. It can be used to drive multiple clock outputs that require lower signal skew. This device is especially useful in applications such as multi-processor systems, where the processor clock timing needs to be closely matched between multiple outputs. In addition, the device offers flexibility in output timing when used in high-speed serial links or in applications where multiple clocks need to be matched in presentation time between multiple outputs.

The IDT49FCT3805SO device is based on a differential crystal or clock driver architecture. This device provides eight differential clock outputs in close synchronization with each other. The main goal of this device is to match the drive clock of the different clocks in timing. The device performs this by buffering a single differential clock input and dividing it up into separate outputs with different propagation delays. The propagation delay of the outputs is based on external passive components such as resistors and capacitors connected to the device. The output timing skew of the device can be adjusted by adjusting the values of the external components.

It also features enabling/disabling for each of the outputs, with a shared enable terminal that can be used to control all outputs simultaneously. The device also offers a power down mode for when the device is not in use, to conserve power. In addition, the device features ESD protection on all outputs. The ESD protection helps to reduce the risk of damage from ESD events such as electrostatic discharge.

The IDT49FCT3805SO device is a versatile and high-performance clock/timing device. It is designed to provide low-skew clock signals to multiple outputs, while offering ESD protection and power down capabilities. Its differential clock driver architecture allows for fine-tuning of the driver delay, and it is specifically designed to reduce skew between outputs. This device is suitable for applications such as multi-processor systems where matching clock timing is critical, or for high-speed serial links where the output timing needs to be closely matched.
