NB2309AC1DTR2G is a clock generator from National Semiconductor, which is used for wide range of applications. It is categorized as Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers and designed for generating high frequency clock pulses. This chip is designed for low power consumption with a maximum power dissipation of only 600 milliwatts.

This NB2309AC1DTR2G chip has two outputs with frequency range from 43MHz up to 110MHz. It is provided with a 3-bit control interface to allow the user to set the output frequencies. There is a wide range of input voltage (range of 1.5 V to 5.5 V) which makes this chip suitable for many applications.

This device can operate in multiple modes, including self-clocked mode, free-run mode, power-down mode and enable/disable modes with externally supplied enable/disable signals. The device provides an external enable/disable signal for controlling the output, which can be used for power saving.

The NB2309AC1DTR2G is designed for low jitter performance and accurate frequency control. Its jitter specification covers a wide range of frequencies, from 10MHz to 110MHz. The device also has a fast lock time and a low operating temperature range of -5°C to 70°C.

The working of this chip is quite simple. It contains an internal voltage-controlled oscillator (VCO) which is used to generate a high frequency clock signal. This signal is then divided by counters to produce the required frequency. This chip contains 3 PLLs, each of which can be used to generate a different frequency. By changing the divider ratio in each PLL, the user can set the frequency of the output and control the phase of the output.

The outputs of the NB2309AC1DTR2G can be used for many applications, such as data processing, analog-to-digital conversion and for driving LCD/LED displays. It is also used as a clock source for digital signal processors and as a frequency-synthesizer for applications such as frequency sweep measurement and phase-locked loop (PLL) tuning.

In conclusion, the NB2309AC1DTR2G is an ideal choice for a wide range of applications, such as data processing, analog-to-digital conversion, LCD/LED displays and frequency sweep measurement. It has an excellent low power consumption and an excellent performance in terms of jitter and lock time. With its wide range of input voltage and its ability to control the frequency and phase output, this chip is an ideal choice for applications which require high frequency clock pulses.
