Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers are used in a wide range of applications, from low power consumer electronics to high end audio and video equipment. The DS1099U-FA/V+T is a highly flexible, high performance clock generator designed to meet the needs of today’s demanding applications. The DS1099U-FA/V+T delivers low jitter, low noise, and superior frequency accuracy over the wide range of output frequencies and voltages required by today’s sophisticated systems.

The DS1099U-FA/V+T uses a patented Frequency Auto-locking Technology (FAT). This technology uses an on-board MEMS resonator that is connected to an on-board oscillator. The oscillator is then connected to a frequency locking circuit, which automatically adjusts the oscillator frequency to match the resonance frequency of the MEMS resonator. By automatically maintaining frequency accuracy, the DS1099U-FA/V+T is able to provide highly accurate, stable clock frequencies across a range of output frequencies.

The DS1099U-FA/V+T has four main operating modes. In Direct Mode, the clock generator can be used as a standalone source of synchronized clock signals, providing precision timing with low jitter and superior frequency accuracy. In PLL Mode, up to eight I2C interfaces can be used to synchronize the on-board oscillator to external clock sources, such as those from a CPU or FPGA. The third operating mode is the Auto-calibration Mode, which uses an on-board programmable timer to automatically adjust the oscillator frequency to match the external clock source. Finally, the Dynamic Fault Tolerance (DFT) mode enables automatic frequency adjustment if the external clock source is not available or present. This ensures that the device can continue to provide reliable clock signals, even if the external clock source is unavailable or changes frequency without warning.

The DS1099U-FA/V+T offers a wide range of features and benefits, including low power consumption, high speed operation, and superior frequency accuracy. The on-board clock generator has been designed to provide the highest performance and exceptional flexibility, allowing users to optimize and customize their clock outputs to meet their specific requirements. The device is fully compliant with the PLL Standard Interface (PIXI) specification, allowing it to be easily integrated into other systems, such as PCIe and Ethernet interfaces.

The DS1099U-FA/V+T is an ideal choice for applications where precision, accuracy, and high performance are required. Its wide range of operating modes, dynamic fault tolerance, and state-of-the-art MEMS resonator make it the perfect choice for a variety of clock, timing and synchronization applications, such as those in automotive, consumer electronics, and industrial systems.
