NB3L553DR2G Integrated Circuits (ICs)

The NB3L553DR2G is a low voltage, 4-bit, fanout buffer/driver, designed for use in high speed memory and clock distributions. Typical applications include clock distribution in personal computers, networking products, and other high speed digital systems. The device is designed to support up to four independent, 3.3 V, low voltage differential signaling (LVDS) outputs. It can also be used to drive a variety of other load types at up to 3.3 V, while maintaining system performance.

The NB3L553DR2G is designed to minimize skew and provide very low output-to-output delay variation (TOCV). The device features low jitter so that system performance and reliability are maximized. The device contains four differential input/output ports that feature 75 Ω termination and have a high differential output impedance. The device outputs are ESD protected and are able to withstand ± 10 kV and IEC 61000-4-2 level 4 ESD (air) discharges.

The NB3L553DR2G is designed to provide a low noise, spread spectrum clock input/output. It incorporates two spread spectrum clock inputs, one for the input clock and one for the output clock, allowing the device to independently adjust the frequency and duty cycle of the output clocks. This improves system jitter, noise immunity and EMC performance. The differential clock inputs feature 75 Ω termination and are ESD protected and are able to withstand ± 10 kV and IEC 61000-4-2 level 4 ESD (air) discharges.

The NB3L553DR2G is an ideal solution for distributed power and ground designs, with each output port featuring separate power and ground connections. The device also supports voltage translation for improved efficiency. The input and output ports are all compatible with a variety of logic families, including CML, TTL, HC and SSTL.

The NB3L553DR2G features a proprietary high speed differential bus architecture that allows each output port to achieve up to 10 Gbps bandwidth with minimum loading. This ensures maximum system performance while maintaining system cost and power budget. The device also supports low propagation delay, delivering output data within 250 ps. The device also features adjustable output voltage and current compliance levels, allowing the user to optimize the logic levels for the specific application.

In summary, the NB3L553DR2G is a low voltage, 4-bit, fanout buffer/driver specifically designed for high speed memory and clock distributions. It is designed to support up to four independent, 3.3 V, low voltage differential signaling (LVDS) outputs, and can also be used to drive a variety of other load types at up to 3.3 V, while maintaining system performance.
