The ZL40220LDF1 clock buffer/driver is a high-performance signal-switching device designed to distribute, fan-out and drive several clocks or data signals. It is fully buffered and features ultra-low propagation delay and low skew between output paths. This makes it ideal for clock/data signal distribution in high-speed digital systems, such as high-speed memory interfaces, digital video solutions, telecom receivers, computer and networking peripherals, embedded systems and personal computers.

The ZL40220LDF1 has two separate outputs that switch in opposite directions, so it can be used for delivering and receiving clocking signals. Internal logic allows the outputs to be enabled and disabled from the same control logic signals. This enables the user to easily configure the clock distribution network.

The ZL40220LDF1 comes in a 24-pin TSSOP package, making it very compact and saving board space. It features an adjustable voltage range of 2.0V to 5.5V, enabling it to work in a wide variety of systems. The device also has a high side disable pin, which allows it to be turned off when not in use, for increased power savings.

The ZL40220LDF1 has a maximum operating frequency of 333MHz, making it suitable for very high speed applications. It is also compliant with JEDEC and I2C standards, making it compatible with most systems. The device also features ESD protection, which helps to protect it from static electricity.

The ZL40220LDF1 works on the principle of transforming clock signals from one form to another. The device takes an input clock signal and buffers it to both the positive and negative outputs. The positive output then has a fractional delay applied before it is output, while the negative output is given an additional fractional delay. This allows the clock to be distributed to multiple devices with a precise, symmetrical delay between the outputs.

The ZL40220LDF1 is ideal for clock/data signal distribution in high-speed digital systems, such as high-speed memory interfaces, digital video solutions, telecom receivers, computer and networking peripherals, embedded systems and personal computers. Its ultra-low propagation delay and low skew between output paths ensure precise, reliable clock distribution in these systems.
