The PI6C49X0204BWIE is a quad differential clock buffer belonging to the Clock/Timing - Clock Buffers, Drivers group. It provides a low-skew, high-performance differential solution for multiple clock and data distribution applications. This device is ideal for applications requiring multiple copies and buffering of a differential reference clock on high-speed interface cards and in other advanced clock distribution systems. With its fully differential output, the PI6C49X0204BWIE improves system performance compared to other clock buffers that use a single-ended output, thus making it suitable for data transmission applications.

The PI6C49X0204BWIE has an operating range of 0°C to 70°C and a supply voltage of 3.3V. It is designed to operate over a frequency range of 4.1 to 250MHz. This buffer has an optimal impedance matching and output drive capability to ensure maximum signal integrity and EMI reduction. The device provides two pairs of output pads and two pairs of output ports which can be customized to support different configurations and applications. This product also offers improved propagation delays, skew, jitter, and noise.

The main application field of the PI6C49X0204BWIE includes high-speed point-to-point, bus topology interfaces and high-speed clock distribution for multiple applications. This buffer is suitable for use in buffering any low-frequency or high-speed clock signals, such as clock and data signals in systems utilizing PCIe, SATA, USB, and Ethernet. It is also suitable for buffering data from ASIC/ASSP/FPGA-to-ASIC/ASSP/FPGA interconnections, mezzanine cards, circuit boards, and complex, high-speed systems.

The working principle of the PI6C49X0204BWIE is based on combining two independent inverters in a differential pair. Each pair of outputs is independently converted and buffered by two identical inverters that share a common clock input. The differential-pair inverters are designed to provide low-power and low-cost solutions for high-speed clock distribution. The design of the inverters is optimized to provide low skew, jitter, and noise over a wide range of clock frequencies. The outputs of the device are also rail-to-rail, meaning that the voltage is close to the Vcc/Vdd supply voltage when the clock frequency is low, and it is adjusted to match the varying input clock frequency when the clock frequency is high.

The PI6C49X0204BWIE is an important device for advanced clocks, data transmission, and distribution applications. Its fully differential output and low-skew, high-performance design make it well-suited for applications requiring multiple copies and buffering of clocks and data signals. The device is robustly designed and has proven to be reliable and to provide maximum signal integrity in a wide variety of applications.
