The 89H22NT16G2ZBHLG is a frequency synthesizer and clock generator designed with an advanced Quadrature Clock Generator (QCG) architecture technology. With advanced features, customizable I/O, and an optimized low power mode, the 89H22NT16G2ZBHLG makes it ideal for a variety of applications, such as digital TV, cellular and wireless transceivers, medical instruments, and precision industrial automation. Its advanced features make it even more suitable for mission critical aerospace, defense, and industrial applications.

The 89H22NT16G2ZBHLG uses a fourfold architecture for generating frequency synthesis, timing, and synchronization signals. This architecture includes a High Frequency Clock Generator (HFCG) for generating the reference or master clock, a Quadrature Clock Generator (QCG) for generating the periodic non-overlapping clock signals, an Analog Frequency Synthesizer (AFS) for generating the programmable multifrequency outputs, and a Phase Locked Loop (PLL) for matching the outputs to the user\'s application requirements.

The 89H22NT16G2ZBHLG High Frequency Clock Generator uses a wide range of input frequencies in a wide variety of crystals, oscillators and voltage controlled oscillators (TVCOs) to generate the master reference clock. The output clock frequency is adjustable from 10kHz to 100MHz, supporting both the differential and the single-ended signal outputs. The internal clock buffers enable the 89H22NT16G2ZBHLG to have an extremely low jitter performance.

The 89H22NT16G2ZBHLG Quadrature Clock Generator (QCG) is the basis for providing a non-overlapping clock signal. This feature is necessary for use in modern communications applications, such as in synchronous communication links, TDMA, and GSM systems. The signal output of the QCG is PECL/LVDS compatible. The signal levels and signal swing can also be software programmable.

The 89H22NT16G2ZBHLG Analog Frequency Synthesizer (AFS) is a low jitter clock synthesizer designed to generate a wide range of output frequencies up to 200MHz. The synthesizer can be tuned to any frequency in the range of 8kHz to 200MHz, which can be adjusted in any kind of step size from 100kHz (LFSR) to 300kHz (Fugas). The AFS also offers an adjustable voltage gain to improve the accuracy of the frequency synthesis.

The 89H22NT16G2ZBHLG Phase Locked Loop (PLL) is the fourth building block for the 89H22NT16G2ZBHLG synthesizer system. The PLL is designed to match the phase and frequency of its output signal tothe phase and frequency of its input reference clock, enabling the 89H22NT16G2ZBHLG to perform as a frequency synthesizer and clock generator. The PLL also ensures a high degree of output accuracy, as well as excellent phase noise characteristics.

The 89H22NT16G2ZBHLG is designed to provide a reliable and fast solution for a wide range of clock and timing applications. Its advanced high frequency clock generator, quadrature clock generator, analog frequency synthesizer, and phase locked loop combine to provide a low jitter, high precision output. It is an ideal choice for mission critical aerospace, defense, and industrial applications, as well as a wide range of consumer applications, including digital TV, cellular and wireless transceivers, medical instruments, and precision industrial automation.
