NB7VQ14MMNHTBG Integrated Circuits (ICs)

The NB7VQ14MMNHTBG is a high-performance, low-noise, low-skew fanout buffer with 14 low-skew and seven outputs. This product belongs to the category of Clock/Timing - Clock Buffers, Drivers, which is designed to meet the stringent timing requirements of SONET and other high-speed communications networks.

This buffer is capable of distributing high-speed clocks to a variety of system elements with low-skew and low-jitter performance. Its output can be used to drive up to seven clock sources with low-skew differential signal pairs. The NB7VQ14MMNHTBG is designed to support the timing requirements of 200 MHz systems and is capable of providing a 15 ns rise/fall time at 140 MHz.

The NB7VQ14MMNHTBG is designed for use in a variety of applications such as SONET/SDH, AVSIONET, Digital Video Interconnects, Gigabit Ethernet, ATM, high-speed PCI, and other applications where low-skew and low-jitter is critical. The NB7VQ14MMNHTBG is useful in applications where multiple outputs are needed while maintaining accurate timing requirements such as in clock fanout, de-skew, static phase shifting, and noise suppression.

The working principle of the NB7VQ14MMNHTBG is based on the use of low-skew and low-jitter TTL compatible devices that are driven by an internal crystal oscillator. The input clock is divided by an internal divide-by-two circuit and provided to an output fanout circuit. The fanout circuit consists of multiple low-skew and low-jitter devices that are accurately timed with the internal oscillator.

The NB7VQ14MMNHTBG provides seven low-skew outputs that operate with tight timing specifications. The outputs have a 3.3V swing and have a typical jitter of 60 picoseconds. The output skew between outputs is guaranteed to be less than 4 nanoseconds and the output-to-output skew is guaranteed to be less than 265 picoseconds. The input-to-output delay is guaranteed to be less than 5 nanoseconds.

The NB7VQ14MMNHTBG also features an input enable control that enables the output signals to be disabled or enabled. The enable signal is used to control the enable/disable of the outputs. The enable control is also useful for synchronization with other devices as well as for controlling the power consumption of the buffer. The NB7VQ14MMNHTBG is available in a compact 24pin SOIC package, allowing it to be used in limited space applications.

In summary, the NB7VQ14MMNHTBG is a versatile and reliable low-skew and low-jitter fanout buffer designed to meet the stringent clock requirements of a variety of applications such as SONET/SDH, AVSIONET, Digital Video Interconnects, Gigabit Ethernet, ATM, and PCI. The output skew between outputs is guaranteed to be less than 4 nanoseconds and the output-to-output skew is guaranteed to be less than 265 picoseconds. The NB7VQ14MMNHTBG also features an input enable control that enables the output signals to be disabled or enabled. The NB7VQ14MMNHTBG is an ideal choice for applications requiring low-skew and low-jitter fanout buffer solutions.
