Additional Details

The IDT49FCT3805QGI is specifically engineered to meet the demanding requirements of high-speed digital systems. Its low skew characteristics are crucial for maintaining signal integrity in synchronous designs. The high drive capability ensures that the clock signals are strong enough to reliably drive multiple loads without significant signal degradation. The device operates at 3.3V and supports input clock frequencies up to 200 MHz. The QFN (Quad Flat No-leads) package offers a small footprint and excellent thermal performance, making it suitable for space-constrained applications. The output enable control allows designers to disable the outputs, which can be useful for system testing or power management during idle states. This clock buffer/driver is commonly used in applications where precise and reliable clock distribution is essential for optimal system performance.
