The 89H22NT16G2ZBHL8 is a type of clock generator, phase-locked loop (PLL), frequency synthesizer, and other timing components which have been integrated into a single chip. This integrated timing device is used primarily in the telecommunications and clock-applied applications. As with any clock generator or frequency synthesizer, this device is responsible for generating precise timing pulses, driving clock distribution networks and controlling the timing of system operations.

Application Field

The 89H22NT16G2ZBHL8 is designed for telecommunications applications such as network routers, switches, multiplexers and optical networks. It is also used in clock-applied applications such as clock-controlled switching networks, clock multiplication and distribution networks, clock synthesis networks, frequency synthesizers, and other timing applications.

Working Principle

This integrated timing device is based on the simple PLL principle: a combination of a frequency detector and a voltage controlled oscillator. The frequency detector measures the input frequency and within an adjustable loop bandwidth adjusts the reaction at the output to a desired output frequency. The VCO is used to generate the output frequencies, which will then be selected by an input frequency selector. Furthermore, the 89H22NT16G2ZBHL8 has a set of internal digital frequency dividers and counters which allows for the generation of precise output frequencies from a single reference frequency.

The 89H22NT16G2ZBHL8 contains an internal clock generation scheme which is used to generate the clock pulses used for the internal logic of the device. This clock generator system is based on a pulse width modulation (PWM) technique which uses multi-level sine waves and adjustable frequency dividers. This clock generation technique is responsible for generating precise clock pulses which will then be used by other components as the system clock reference.

The 89H22NT16G2ZBHL8 also contains a set of special counters, dividers, and other elements which are used to program the device for precise timing applications. These elements are connected to the VCO output to detect the reference frequency, calculate the precise output frequency, and adjust the PLL loop parameters.

The 89H22NT16G2ZBHL8 is capable of generating clock frequencies ranging from 10 KHz to 200 MHZ, as well as providing precise synchronization of highly synchronized clock frequencies. In addition, its low power consumption, small footprint, and low cost make it an ideal choice for use in many different types of applications.
