The DS1085LZ-25B2+ is a versatile and reliable clock generator, programmable frequency synthesizer, phase-locked loop (PLL) IC developed by Texas Instruments. It is one of the most advanced clock and timing ICs due to its extremely high frequency input, output and PLL execution speed; superior holdover performance and internal Phase-Frequency Detector (PFD) and loop filter compensation. The versatility and wide range of options of the DS1085LZ-25B2+ make it suitable for a number of applications requiring accurate timing.
The DS1085LZ-25B2+ has a wide range of input frequencies from 10MHz to 300MHz, but also offers an integrated crystal oscillator (XO), which ensures that the part can generate output frequencies from as low as 31MHz up to 300MHz. The part has three outputs, two single-ended outputs and one adjustable differential output. All three outputs can be programmed to frequencies anywhere between 31MHz and 300MHz with a resolution of better than 1ppm.
The integrated PLL of the DS1085LZ-25B2+ allows the part to synthesize frequencies with a high degree of accuracy and resolution. The part offers an integrated PFD and loop filter components, enabling the part to lock on to any input frequency without prior knowledge of the reference frequency or loop filter settings. The PFD features a proprietary architecture to ensure jitter performance that is difficult to achieve with traditional PLL designs. This combination of a fast lock time and improved jitter performance make the DS1085LZ-25B2+ an ideal solution for applications where extremely stable and accurate clock signals are required.
This versatile IC is suitable for a number of applications from low cost consumer electronics such as WiFi routers and Bluetooth adapters, to demanding professional equipment where precise timing and frequency control is paramount such as high end professional audio playback systems and test measurement equipment. Additionally, the part is able to generate precise frequencies for mobile/cellular telecommunications, medical equipment, and a myriad of consumer, industrial and automotive electronics.
The DS1085LZ-25B2+ is a hybrid of a clock generator and programmable frequency synthesizer. In addition, it houses an array of features, all of which improve the re-programmability, frequency flexibility, and stability of the IC. Such features include crossed overtone crystals, crystal automatic monitoring and trimming, frequency offset control, jitter performance, and phase noise reduction. All these features enabled the DS1085LZ-25B2+ to generate precise and stable frequencies with little effort.
A special feature of the DS1085LZ-25B2+ is the integrated clock synchronization circuitry, which allows the clock generator to sync with an upstream clock source. This allows the IC to lock on to a global timing reference to ensure that the generated clock is phase aligned with the incoming reference clocks. This feature also enables improved peak jitter performance over conventional PLL designs.
In conclusion, the DS1085LZ-25B2+ is a highly versatile IC designed for a range of demanding frequency generator applications. It offers an extremely wide range of input and output frequencies, excellent frequency stability and jitter performance, and additional features such as clock synchronization. This makes the part ideal for any application requiring reliable timing and frequency control.
