The PLL1707DBQRG4 is a world-wide available clock generator from ICS (Integrated Circuit Systems). It is an integrated programmable clock generator with an internal Phase Locked Loop (PLL), consisting of high-performance, low-current integrated circuits. It provides up to four independent, frequency-agile outputs. This device features low supply current and a high accuracy reference with low jitter. It is designed to support a wide variety of applications such as telecommunications, computers, modems, and base stations.

The PLL1707DBQRG4 has a broad range of applications, but it is mostly used in networking, telecommunications, and computer equipment. It is capable of generating high-speed synchronized clock signals, providing jitter-free outputs, and providing reliable power-up characteristics. It is also suitable for use in data communication systems, including GSM, W-CDMA, and 802.11b/g/n, as well as in other router, switch, and firewalling products.

The PLL1707DBQRG4 clock generator brings a variety of advantages over traditional quartz crystal oscillators. It offers lower jitter, a smaller form factor, and greater stability. In addition, it provides efficient power management, output drive capability, and comprehensive diagnostic features.

The clock generator features a field-programmable PLL and reference, enabling clock frequencies from 19.2 KHz to 600 MHz to be generated from different divided fractions of the PLL. The clock generator is programmable via an I2C slave interface, making it ideal for mass production. Once programmed, the output frequencies are stored in non-volatile memory and are guaranteed after power-on.

The clock generator is based on the VCO (Voltage Controlled Oscillator), PLL (Phase Lock Loop) and fine-tune circuitry. The VCO is the heart of the clock generator and is made up of a tuned circuit, which is composed of a resistor, capacitor, and inductor. When voltage is applied to the tuned circuit, it starts oscillating at its resonant frequency. The frequency of the oscillation is determined by the values of the components in the tuned circuit. The PLL then controls the frequency of the VCO output by varying the applied voltage. The fine-tune circuitry further adjusts the frequency of the output.

The PLL1707DBQRG4 can be used in all types of applications requiring high-speed, low jitter and frequency-agile clock signals, including high-speed data communication systems, network equipment, and base stations. It offers a range of capabilities, allowing users to build high-performance systems using the latest technologies.
