89H16NT8BG2ZCHLI8 is a clock generator, phase-locked loop (PLL) & frequency synthesizer integrated circuit (IC) used in a variety of applications. It has a low power consumption, a high-level of integration, and offers excellent performance in terms of group delay variation, jitter, and EMI/EMC.

In terms of applications, 89H16NT8BG2ZCHLI8 is used in digital television and cable set-top box (STB) systems, general-purpose digital meters, multicore hot dog processors, Blu-ray players, surveillance systems, telecom base stations, and to generate operating clocks for wireless communications applications.

The clock generator of the 89H16NT8BG2ZCHLI8 can generate a wide range of frequencies from a reference. It has a frequency range from 6.25MHz to 800MHz, and a frequency resolution of 32 steps. The PLL has a VCO tuning range from 400MHz to 1200MHz, and a VCO output range of 6 to 800MHz. The frequency synthesizer has a wide oscillating range, from 100kHz to 10GHz, and an adjustable output current up to 10mA.

The 89H16NT8BG2ZCHLI8 contains a crystal oscillator, a low-noise VCO, a phase frequency detector, a pre-divider, a charge pump, a frequency divider, and a voltage-controlled oscillator (VCO). The crystal oscillator provides a reference frequency for the PLL, whose output is then divided to obtain the desired output frequency. The pre-divider divides the reference frequency before it is sent to the PLL frequency detector. The charge pump generates an error signal based on the frequency difference between the reference frequency and the VCO output frequency. It then feeds the error signal to the VCO, which adjusts its output frequency. Finally, the frequency divider divides the VCO output frequency to obtain the desired output frequency.

In terms of performance, the 89H16NT8BG2ZCHLI8 can operate at a maximum frequency resolution of 300ps and offers an excellent jitter of 0.5ps rms. It has a low power consumption, with a typical consumption of 1.3-3.3 mW at input frequencies of 1kHz-12MHz, and a maximum consumption of 15-20 mW at input frequencies of 324-1248MHz. The 89H16NT8BG2ZCHLI8 also offers excellent EMI/EMC performance, with a low EMI susceptibility of less than 10dB in the frequency range from 0.5-10GHz.

In summary, 89H16NT8BG2ZCHLI8 is an IC used in a wide range of applications, including digital television and cable set-top box systems, general-purpose digital meters, multicore hot dog processors, Blu-ray players, surveillance systems, telecom base stations, and to generate operating clocks for wireless communications applications.
