The IDT49FCT3805SOI is a high-speed fanout buffer from Integrated Device Technologies, a leader in the development and production of high-performance semiconductor memory products. The buffer is designed to work in conjunction with a variety of synchronous and asynchronous digital signals, providing reliable, cost-effective fanout designs with minimal propagation delay.

The IDT49FCT3805SOI is a low power device designed to support both low-voltage and high-frequency operations. It is capable of fanning out one high-speed input signal to sixteen compatible outputs. The use of an integrated buffer provides superior signal integrity and noise immunity across the clock frequency range.

The IDT49FCT3805SOI is for use in synchronous clock buffers driving and distributing high-frequency clock or data signals. It provides high-speed, low-skew fanout of a single clock signal with minimal propagation delay. The device is fully compliant to the IEEE 1149.1 standard, and is compatible with 3.3V, 2.5V, and 1.8V logic levels.

The buffer is extremely low powered, drawing only 19 μA of static current for the entire buffer core. This low power consumption makes it ideal for use in power sensitive applications, such as portable and embedded systems. In addition, the buffer requires only 0.3 Wo of drive current, making it suitable for use with low-capacitance devices.

The IDT49FCT3805SOI also features an integrated data output buffer, allowing it to be used as an output buffer in applications where multiple data lines require buffering. The buffer is designed to drive a maximum of 8 kΩ of PCB trace, allowing it to easily fan out high-speed data signals.

The buffer is also capable of handling single-ended data interfaces, with the integrated output buffer allowing direct conversion of a single-ended signal to differential. This feature is ideal for applications with multiple output buffers, as it allows direct connection of a single-ended source.

In addition, the IDT49FCT3805SOI has two compliment feature pins for active-low output enable and toggle reset. The active-low output enable pin is used to completely disable the device, and the toggle reset pin allows for resetting the device using edge times that are faster than the chip’s setup and hold times.

The IDT49FCT3805SOI is an ideal solution for fanout of single-ended and/or differential signals in high-speed applications. The device is optimized to reduce propagation delays and skew, while providing low power consumption, high-frequency operation, and exceptional signal integrity. The buffer is designed to handle a range of clock frequencies, ensuring reliable operation in applications ranging from conventional digital systems to high-performance, power-sensitive designs.
