The MAX9491ETP080+T are clock generators, phase-locked loops, frequency synthesizers, and time processors from Maxim Integrated’s Timing Solutions. The devices provide clock generation and synchronization for various applications, such as video, audio, and cellular base station applications.

The devices integrate both frequency synthesis and timing algorithms for applications that require multiple clock outputs. The internally generated high frequency clock can be used to derive other clocks with programmable frequencies or have direct outputs from the IC. The devices can be programmed to select from one of several configurable output frequencies and time bases.

The MAX9491ETP080+T can produce clocks up to 800MHz in order to provide systems with the power they need to process complex audio and video signals. Additionally, the devices can support a variety of different audio and video standards, including AES/EBU, SDI, and DVB-ASI. In order to provide maximum flexibility to designers, the MAX9491ETP080+T also provides two different voltage supply processes.

The devices also incorporate an on-chip phase-locked loop (PLL) to allow for clean signal synthesizing. The PLL circuit is responsible for providing a clean signal for the multiple frequency clocks, and for controlling the frequency of the reference signal accurately. The MAX9491ETP080+T have adjustable system parameters such as PLL bandwidth and division factor that can be used to optimize system performance.

Additionally, the devices offer a host of features such as spread spectrum operation, comprehensive control and monitoring features, as well as protection features such as slew-rate limiting, reverse-barrier protection, low-power shutdown, and over-temperature protection.

The MAX9491ETP080+T are designed to operate in the industrial temperature range (-40°C to +85°C) and, when compared to other timing solutions, exhibit superior power, size, noise, and thermal performance. The devices come in different packages, including QFN and BGA, which are designed to reduce the footprint of the application.

In summary, the MAX9491ETP080+T are clock generator, phase-locked loop, frequency synthesizer, and timing processor devices that offer performance, flexibility, and protection. Combining the devices with other components of the Maxim Integrated Timing Solutions provides systems with the power and precision for processing complex audio and video signals.
