The PLL1706DBQ from Texas Instruments is a high-performance programmable integer-N frequency synthesizer device. It offers low phase noise, excellent spurious and jitter performance, and fast, programmable output frequency tuning for up to four outputs. The synthesizer also includes an integrated phase-locked loop (PLL) and voltage-controlled oscillator (VCO) subsystem, a series of digital counters, and an optional serial port interface.

Application Field

The PLL1706DBQ is typically used in high-speed wireless, optical communications, Ethernet, and data conversion applications, as well as in base station receivers, custom ASICs, and reference designs. The device is designed to support Gigabit Ethernet, and Wi-Fi LAN, WAN, and microwave/millimeter-wave applications, along with high-speed data conversion and frequency synthesis.

Working Principle

The PLL1706DBQ features an extremely low noise architecture with an integrated VCO and PLL subsystem. The integrated PLL provides high-accuracy frequency tuning and jitter performance without any need for external components. The device\'s integrated digital counters allow for programmable output frequency tuning for up to four outputs.

The device also includes an on-chip reference clock, a serial port interface for programming, and an optional power-down feature. The serial port interface allows for fast and easy configuration of the device parameters, as well as a quick response to changing requirements.

The PLL1706DBQ is built on a programmable logic device. This allows users to customize their design to their specific requirements and incorporate features such as clock tree synthesis, phase locking, noise cancellation, and power savings.

The device\'s low phase noise and excellent spurious performance make it suitable for a wide range of applications requiring accurate frequency synthesis. The device can be used in both standalone and embedded applications, providing cost-effective, low-power and high-performance frequency synthesis.
