NB2305AC1DTR2G is a clock generator, phase-locked loop (PLL), and frequency synthesizer integrated circuit. It is intended to provide clock sources and timing related functions for a variety of applications.

Application Field

This device provides rail-to-rail output current drive on all pins for applications such as telecommunications, industrial controls, computer, and peripherals. It is mainly used for communication systems, namely for frequency synthesizing, clock generating, and jitter performance. It is also designed for high-speed serial applications, providing high-speed inputs that are fundamental building blocks in many CMOS ASIC\'s, FPGA\'s, and microprocessors. In addition, it is well-suited for high performance amplifier applications, since its fully-differential output design can directly drive high-speed actuators and motors. It is also useful for a wide range of applications such as SDRAM, PCM/CD-ROM, Ethernet and digital audio systems.

Working Principle

The working principle of this device is based on a divide-by-N PLL loop, which is composed of a Voltage-Controlled Oscillator (VCO), a phase/frequency detector, and a lowpass filter. The VCO is the core element of the PLL which generates the final output frequency. It can generate a wide range of frequencies, ranging from 10 kHz to 200 MHz.

The frequency of the VCO can be adjusted by varying one of the loop parameters, such as the loop filter or the reference frequency. The reference frequency is typically provided by a crystal oscillator or a window oscillator. The output of the reference frequency is compared to the generated VCO frequency and a phase/frequency detector produces an error signal that drives the loop filter. This error signal is ultimately used to adjust the VCO frequency.

In addition to its basic functions, the NB2305AC1DTR2G also includes a central control element which allows users to program the device with multiple clock frequencies and configurations. This makes it ideal for systems that require dynamic clock configurations or require the support of multiple clock frequencies. The control element is programmable through a serial interface, which can be connected to an external microcontroller or FPGA.

The NB2305AC1DTR2G is the perfect solution for applications that require a reliable and low-cost clock generator and frequency synthesizer. It is designed to provide a broad spectrum of features, such as rail-to-rail outputs, high accuracy, wide frequency range and flexibility.
