2305NZT-1DCG – Clock Buffers, Drivers Application Field and Working Principle

The 2305NZT-1DCG is a performance-optimized clock buffer, driver, ideal for various high-performance, high-speed timing applications. The device improves signal integrity when physically separating devices or systems. It stretches the distance between digital devices, propagation delay, and higher isolation without compromising the data integrity since it redistributes the clock signal at the output timings.

Key Applications

The 2305NZT-1DCG is used in a wide range of diverse higher-speed timing applications, such as ASICs, FPGAs, processors, SerDes and other performance-critical, high-performance digital subsystems. The 2305NZT-1DCG is a suitable solution for a variety of designs, including networking, communication, storage and embedded applications such as Data centers, Base stations, Automotive, MIL-Aero, Industrial automation and other clock signal intentional signal conditioning applications.

Working Principle

The 2305NZT-1DCG provides performance-optimized clock and data distribution. It is a fully integrated device featuring four symmetric differential inputs with clock reference input pins and four outputs. The clock reference or reference oscillator input is used to setup the output timing and is typically driven by a differential high frequency crystal oscillator (XO) or an integrated voltage-controlled oscillator (VCO). All of the four differential outputs can be used simultaneously to provide LVCMOS output levels from the XO and VCO. With the outputs arranged in two pair of outputs, the device can also be used for multi-bitrate clock distribution.

The device uses the clock reference input to generate clock outputs that dampen the peak–to–peak jitter from the input. It features rise/fall time controlled outputs with a maximum output frequency of 200 MHz which match the clock reference input nice and cleanly. The buffer Driver also features programmable duty cycle output selectable from 50/50 to 90/10. Finally, the outputs of the 2305NZT-1DCG can be further optimized using the available control programming options, such as output amplitude, drive strength and frequency.

The 2305NZT-1DCG is designed to allow an output frequency range up to 200 MHz and programmable duty cycle outputs, without the need for an external loop filter, so the user can easily adjust the output frequency, duty cycle and drive strength to ensure seamless operation. The 2305NZT-1DCG is also designed to provide low latency, high noise immunity and low RMS jitter to ensure excellent signal integrity and performance in high performance, high data rate timing applications.

Conclusion

The 2305NZT-1DCG is a performance-optimized clock buffer and driver that can be used in a variety of high-speed timing applications. With its ability to extend the distance between digital devices and reduce propagation delay without sacrificing data integrity, the 2305NZT-1DCG provides an ideal solution for networking, communications, storage, automotive, military and industrial automation applications.
