The PLL1705DBQR device is a dual clock-frequency generator with a Frequency Division capability and a wide range of available frequencies. It is a versatile device that is used in several applications.

The PLL1705DBQR clock-frequency generator is composed of two integrated circuits. The first IC contains two Frequency Synthesizers (FSs) and a Phase-Locked Loop (PLL). The second IC includes two digital-divider units, using a digital frequency-division approach. It has the capability to divide a single input frequency (up to 300 MHz) in two independent outputs according to the selected dividing factor, allowing a wide range of frequency outputs.

The PLL1705DBQR device can be used in various applications such as clock-recovery and clock-distribution. The FSs are the primary components used for clock-recovery solutions, taking the reference clock and producing the exact frequency needed by the circuit. The PLL restricts and locks any frequency changes according to the input reference frequency, thus providing a clock-stable output. The Digital-Divider unit follows every change in Reference Clock frequency, keeping the output frequency unchanged.

The working principle of the PLL1705DBQR is based on the PLL concept. An external clock is used as the reference and supplied to the FSs that process the input frequency and feed the output to the PLL block. The PLL is composed of a Charge Pump and a Voltage-Controlled Oscillator (VCO). The Charge Pump modifies the VCO frequency depending on the input, thus providing the exact requested frequency at the output. The Digital-Divider unit divides the output frequency according to the selected dividing factor. The PLL1705DBQR has a wide range of available frequencies and is capable of 2.5 GHz frequency, depending on the reference input.

The PLL1705DBQR device is suitable for many applications, including clock-recovery solutions, clock distribution, and portable electronics. The device is widely used in applications such as servers, base stations, routers, and media players. The device can also be used in embedded designs, where generated signals are required. Furthermore, having two outputs allows it to be used as a dual-frequency generator in applications such as digital video signals, monitor synchronization, and encoding/decoding applications.

In summary, the PLL1705DBQR is a dual clock/frequency generator with Frequency Division capability and a wide range of available frequencies. It is composed of two integrated circuits and is suitable for various applications such as clock-recovery solutions, clock distribution, and embedded designs. The PLL1705DBQR is a versatile device that can be used in a wide range of applications.
