NB3N111KMNG

The NB3N111KMNG is a clock buffer and driver from Texas Instruments. This device is used to reduce power consumption by providing five copies of an input clock with drive capability and adjustable rise and fall times. It also allows for one clock to be passed through with low skew. This device can be used in various applications, and the main ones are discussed below, along with the working principle.

Application Fields

The primary applications for the NB3N111KMNG are those requiring high speed clock generation, such as clock distribution networks, MCMs, and chip-to-chip communication links. It is also suitable for use in systems with high noise or moisture levels, as the device can reduce clock skews. In addition, the adjustable rise and fall times make it ideal for applications that require precise timing.

The NB3N111KMNG is typically used in clock buffers, clock drivers, and cross-point switches. Clock buffer applications include clock distribution networks, while clock driver applications includes communications links and networking equipment. In addition, the NB3N111KMNG can be used in cross-point switches to multiplex multiple clock inputs to multiple outputs. These applications require low power consumption and adjustable rise and fall times.

Working Principle

The NB3N111KMNG utilizes an input clock signal to produce five output clocks. The input clock is used to drive a four-stage synchronous divider, resulting in five output clocks with adjustable divide ratios from 1:1 to 4:1. These clocks are then passed through a programmable gain buffer that is used to adjust the drive strength. The output clocks are also subject to adjustable rise and fall times, which can be set for the different divide ratios.

In addition to the four-stage synchronous divider, the NB3N111KMNG also has a clock combiner that is used to reduce clock skew and reduce power consumption. The clock combiner combines the input clock and the five output clocks in a way that minimizes clock skew and reduces power consumption. The clock combiner also allows for one clock to be passed through with low skew.

Overall, the NB3N111KMNG is a clock buffer and driver that is used to reduce power consumption and provide precise clock timing. It is commonly used in applications such as clock distribution networks, MCMs, and chip-to-chip communication links. The device utilizes an input clock to produce five output clocks with adjustable divide ratios, adjustable rise and fall times, and clock skew reduction.
