PI49FCT3803LE is a kind of Clock/Timing - Clock Buffers, Drivers. It is designed for high speed applications such as Media Oriented Systems Transport (MOST150) and Gigabit Ethernet. The device distributes one or two reference clocks (REFCLK1 and REFCLK2) to up to eight respective pairs of differential outputs (Q1 and Q1 /, Q2 and Q2 /, etc.). Each of the differential outputs pair is operated at data transmission rates, up to up to 1.25GHz. The part\'s package includes a 24-TQFN.

The high-bandwidth features of the PI49FCT3803LE, together with low power operation, are ideal for high-speed data networks and serve as an ideal alternative to large FPGA or ASICs solutions. The device contains multiple sets of output buffers in the same package and a clock multiplication function. This helps to reduce design complexity and board space.

The PI49FCT3803LE device reduces board complexity and size by providing a low latency, high bandwidth, low power Clock Buffer, with both wide-bandwidth clock buffering and Divide-by-2/4/8/16/32 capabilities. The device distributes one or two reference clocks (REFCLK1 and REFCLK2) to respective differential output pairs (Q1 and Q1 /,Q2 and Q2 /, etc.). It also offers four independent, dynamically configurable frequency dividers that can divide an input clock signal by 2, 4, 8, 16 and 32.

The device supports multiple Clock Outputs, with wide Frequency Division ranges. The divisions range from 2 to 32, allowing a maximum of 32 total output clocks per clock input. The device can also be used as a Cross Clocking Switch, with dynamic and static phase trimming. The PI49FCT3803LE has a wide input clock range of 77-500MHz. It is ideal for use in point-to-point communication applications that require high speed, low latency performance.

In short, the working principle of PI49FCT3803LE is based on the transmission and/or reception of one or two reference clocks. This device distributes one or two reference clocks (REFCLK1 and REFCLK2) to up to eight respective pairs of differential outputs. A comprehensive range of frequency dividers with up to 32 divisions allow the clock outputs to be independently configured to produce a total of 32 output clocks per clock input. In addition to clock buffering, the device supports dynamic phase trimming, allowing for clock adjustment in order to reduce skew delay between multiple channels. This helps to ensure a fast, low latency transmission along the data network.

The PI49FCT3803LE is designed for applications that require high speed clock distribution and data transmission, such as those seen in automotive infotainment and communications, consumer electronics, and telecommunications. Its high bandwidth, low power, and low latency features make it suitable for a wide range of applications, such as Media Oriented Systems Transport (MOST150), Gigabit Ethernet and other video/audio applications.
