The 8T49N004A-067NLGI8 is a clock generator, PLL, frequency synthesizer module from IDT. This multifunctional device combines a PLL for frequency synthesis with programmable system clocks to provide the necessary frequencies for modern computer, communication and data acquisition systems. This device offers cost savings by reducing the number of external components, allowing designers to quickly and easily expand their application’s capabilities with minimal effort.The 8T49N004A-067NLGI8 is constructed on a single 5mm x 5mm QFN (Quad Flat No Lead) package. This package facilitates integration into a wide range of applications, allowing for substantial reductions in the number and size of components. IDT\'s PLL technology allows the 8T49N004A-067NLGI8 to produce up to seven separate outputs with frequencies ranging up to 437.5MHz. These outputs can be configured by the user via the device\'s companion software, which also provides diagnostic features and a graphical user interface to simplify the programming process.The 8T49N004A-067NLGI8 enables system designers to generate a wide range of frequencies with a single device. This device uses digitally controlled oscillators (DCOs) to generate its clock signals while providing superior jitter performance and exceptional frequency stability. In addition, the 8T49N004A-067NLGI8 provides an output divider that can divide an incoming clock by a fractional value to achieve lower output frequencies without needing an external component.The 8T49N004A-067NLGI8 also contains a PLL, allowing the user to synthesize a wide range of output frequencies from a single crystal reference. The PLL includes adjustable control parameters, such as charge pump current, dedicated VCO lines and loop filter parameters, as well as auto-adjustment functions for easy board layout. This device also integrates a wide range of features to improve system timing, including calibration, delay adjustment, phase-lock loop-shaping, frequency hopping and offset cancellation.The 8T49N004A-067NLGI8 uses mid-range voltage supplies and features low power dissipation. This device requires a single 3.3V CMOS control voltage and provides an on-chip clock adjustment unit that allows the user to fine-tune the clock frequency via an external resistor. The device also offers over-voltage protection, which ensures that it remains fully functional even when operating in an environment with unstable or elevated supply voltages.The 8T49N004A-067NLGI8 is ideal for applications that require low jitter and superior frequency stability, such as digital audio and video broadcasting, mobile communication systems, clock and data recovery, and general-purpose timing systems. This device can be used to generate local system clocks, as well as a wide range of output frequencies with greater accuracy and flexibility than traditional quartz oscillators.
