The CDC339DB device is a low-skew, fan-out Buffer and Driver with low output-enable (OE) leakage. The CDC339DB enables system designers to drive high performance systems with multiple clock sources and multiple frequency and phase synchronization requirements. The device offers two independent outputs of the same phase and frequency or two outputs that are 180 degrees phase-shifted outputs. With its fan-out of five outputs and its low skew, the CDC339DB is ideal for dual clock tree applications requiring high performance and low noise.

The CDC339DB is a dual-input, dual-output Buffer/Driver device specifically designed for clocking and timing applications. It provides two differential input pairs and five differential output pairs, which can be used to power up to five clock signals from a single source. The low-skew, dissipative nature of this device allows for a significant reduction in overall clock tree jitter. The inputs are designed to accept high-frequency clocks up to 500 MHz and provide a low input-to-output delay of 1.5 ns. The outputs are capable of delivering LVDS, CML, LVPECL, and LVHSTL logic levels.

The unique design of the CDC339DB offers enhanced reliability, low power consumption, and low EMI. It features ESD protection on all inputs and outputs, as well as electrostatic discharge protection on the power and ground pins. Additionally, the CDC339DB features a low-power-down mode for power conservation when the device is not in use. The device also features a built-in jitter attenuator that reduces electromagnetic interference and improves noise immunity.

The CDC339DB is ideal for clock and timing applications requiring multiple clock signals and low output-enable (OE) leakage. It provides an optimal solution for distributed clock trees and systems requiring high performance and low noise. The low power consumption and ESD protection make this device suitable for use in high-density applications, where reliability and output-enable leakage are critical factors. Furthermore, the low input-to-output delay, wide frequency range, and jitter attenuating capability make it an ideal solution for applications requiring high-speed clocking and timing accuracy.
