The PLL1707DBQG4 clock generator, also called the low noise wideband frequency synthesizer, is an integrated circuit (IC) developed by Analog Devices, Inc. This PLL is a high performance, wide band frequency synthesizer with low noise and low power dissipation. It is the industry\'s first low noise, fully integrated frequency synthesizer that is capable of operating from DC up to 2.5 GHz. It is also capable of generating wideband modulation signals with low side-lobe levels.

The PLL1707DBQG4 is a highly integrated, low-noise, wideband frequency synthesizer that is designed for wireless communications applications such as CDMA, W-CDMA, GSM, CDMA2000, EDGE, and WiFi. It is ideally suited for 3G/4G base station, mobile handsets, and wireless repeaters. It is also suitable for fixed wireless LAN and cable/sat TV applications.

The PLL1707DBQG4 is a programmable frequency synthesizer with low phase noise, low harmonic and low spurious performance, wide dynamic frequency range and fast settling time. It has an integrated phase detector, low pass filter, loop filter, VCO, charge pump and fractional N divider. It also features a power saving mode that allows the core voltage of the PLL to be reduced and the VCO to be turned off when the PLL isn\'t transmitting.

The PLL1707DBQG4\'s working principle is based on the phase-locked loop (PLL) concept. In a PLL, an external reference source is used to generate a reference signal that is fed into the phase detector which is then compared with a feedback signal from the internal frequency synthesizer. The output of the phase detector is then used to control the internal frequency synthesizer, resulting in an output frequency that is locked to the reference frequency. The PLL1707DBQG4 features low jitter and high loop bandwidth, allowing it to track small changes in the external reference frequency, making it an ideal choice for frequency synthesizers.

The PLL1707DBQG4 is ideal for applications where low power dissipation, low noise and wide dynamic frequency range are required. It is designed for use in mobile handsets, base stations, repeaters, and other wireless communication systems, as well as for cable/sat TV and fixed wireless LAN applications. It also features a power saving mode that allows the core voltage of the PLL to be reduced and the VCO to be turned off when the PLL isn\'t transmitting.

The PLL1707DBQG4 is an ideal choice for a wide range of wireless communications applications, as it offers low noise, low power dissipation, wide dynamic frequency range and fast settling time. By utilizing PLL1707DBQG4, users will be able to achieve reliable wireless communication signals with low noise, wideband frequency synthesis and fast settling time.
