The PI49FCT3807HEX is an integrated circuit designed for applications requiring precise timing and/or wide range clock buffering/ clocking support. The main features of this device are spread spectrum clocking, adjustable destination and fan-out delay, and wide range permutation of source and destination fan-out drive paths. These features make this IC an ideal choice for applications such as media interfaces, AV receivers, DVD players, game consoles, and set top boxes.

The PI49FCT3807HEX is a monolithic integrated circuit that provides frequency synthesizers, clock generators, peripheral logic and memory address and data buses. It has four frequency synthesizers which generate up to 4.7GHz clock frequency. The device can be configured to operate in spread spectrum mode, providing additional robustness to EMI disturbances. It is also capable of providing the following synchronization modes: Non-selective, synchronized, and fine lock. This IC supports a wide range of fan-out drives, from 4-31 with either low timing (1.5ns) or high timing (3.6ns) delays.

The IC also features an adjustable destination and fan-out delay, which can be used to compensate for board trace length between source and destination. This is especially useful in applications requiring high speed clock distribution at the board level, ensuring that all destinations receive the same clock frequency and phase relationships for the best system performance. Demand for multiple clock frequencies is covered too, with the PI49FCT3807HEX capable of providing up to eight clock frequencies in its fan-out paths.

Designed for robust operation, the PI49FCT3807HEX is rated to handle an input frequency range of 6 MHz to 42MHz and is also available as a Military Grade Qualification Variant (MGQV) which is appropriate for Military, Space, and Ruggedized applications. It also meets ENV100-2-2 conditions, greatly reducing the possibility of signal corruptions due to EMI disturbances. The PI49FCT3807HEX is a versatile device, providing clock buffering and wide range of permutation of source and destination fan-out drive paths.

The PI49FCT3807HEX interacts directly with an external clock signal and provides a precision internal clock drive for the user’s local area network. The device performs input validation and translation of the signal in order to protect the source from EMI, output jitter, mismatched loads and overdriving. In addition, the PI49FCT3807HEX also enables multiple source frequencies and accepts different clock divide settings from the source. This boosts the clock availability for the various nodes connected to the LAN.

The PI49FCT3807HEX is a versatile and very useful IC for applications that require precision timing and/or a wide range of clock buffering/clocking support. Its adjustability, combined with its multiple synchronization modes, allow users to create unique configurations based on their specific requirements leading to maximum system performance. This IC is especially useful in media interfacing, AV receivers, DVD players, game consoles and set top boxes.
