The MC100E446FN is an Integrated Circuit (IC) designed to provide clock recovery, jitter attenuation and Cross-point Switching functions across a wide range of applications. Its primary purpose is to eliminate the need to externally provide the necessary clock source often required in clocking designs. The MC100E446FN Clock Recovery, Jitter Attenuation and Cross-Point Switching integrated circuit (IC) offers a complete clock recovery and Cross-point Switching system within a single device. It is designed to provide a cost-effective and reliable solution for systems requiring clock regeneration, jitter attenuation and clock source distribution.

This IC combines a low-noise programmable divider and Spread Spectrum clock recovery circuit with a high-performance adaptive clock recovery and Cross-point Switching circuit. It can provide a clock signal of up to 622Mbit/s, with a jitter attenuation of 1UI (unit interval). The MC100E446FN IC includes a wide range of features and functions that make it suitable for a variety of applications. These include HD/SDI (High Definition/Standard Definition)video, broadcast and professional video, air and space communications, synchronous optical networking (SONET), asynchronous transfer mode (ATM) switching, digital broadcast and digital video broadcast (DVB).

The MC100E446FN IC’s clock regeneration capabilities provide reliable clock recovery and jitterattenuation up to 622Mbit/s. It is capable of extracting a clock signal from a noisy or noisy line, or from a data stream that includes pauses or data errors. The IC can also be used to deskew multiple clock signals, eliminating potential timing mismatches between clock signals by adjusting their phase relationship. The IC also features a programmable edge detection circuit, providing the user with the flexibility to set the edge detection window to control and optimize the clock recovery performance. The IC also allows the user to adjust the gain and bandwidth of the loop filter to match the performance requirements of the application.

The Cross-point Switching capabilities of the MC100E446FN IC allow the user to select two distinct clock output sources, either a recovered clock signal or a programmable range of clean clock sources. The Cross-point Switching circuitry allows the user to switch between two clock frequencies, allowing the IC to sample different signals at different rates. The programmable divider and Spread Spectrum circuit can also be used to modulate the clock signals, allowing the user to utilize the Cros-point Switching circuitry for frequency division or frequency division multiplexing.

In conclusion, the MC100E446FN IC is a versatile and cost-effective solution for a wide range of interface and specialized applications. Its clock recovery, jitter attenuation, and Cross-point Switching capabilities make it suitable for HD/SDI video broadcast applications, air and space communications, synchronous optical networking (SONET), asynchronous transfer mode (ATM) switching, and digital broadcast and digital video broadcast (DVB). Its programmable divider and Spread Spectrum circuit provide the user with the flexibility to set the edge detection window, as well as adjust the gain and bandwidth of the loop filter to match the application’s performance requirements. Finally, the Cross-point Switching circuitry offers the user the ability to choose between two distinct clock output sources, enabling the IC to sample different signals at different rates.
