Clock/Timer - Clock Generator, PLLs, Frequency Synthesizers

SL28PCIE25ALCT is an integrated circuit designed for complex clock-generation applications. It is a high-speed, self-timed, low-power clock generator with a variety of features and modes that can generate low-noise, fixed frequency-outputs. The IC’s high speed and low power consumption also make it suitable for automotive and aerospace applications.

This chip is used to create high-speed clock signals that are phase-locked with an input frequency through the phase-locked loop (PLL) architecture. The PLL block provides a highly accurate phase-control process due to its wide frequency range and precision. The chip integrates clock-generation logic with multiple adjustable parameters to accommodate user-specific requirements. The integrated temperature sensor can also be used for temperature-independent operation.

The SL28PCIE25ALCT can produce clock signals with frequencies up to 2.5GHz with precisely controlled duty cycle, frequency accuracy, and power consumption. It can also generate duty cycles up to 80%. The device features a wide band input supporting up to 8MHz at frequencies up to 2.5GHz with its dual clock spread spectrum outputs.

The SL28PCIE25ALCT integrates several output options offering different user selectable driving styles. These driving styles include LVCMOS, CML, high-speed differential LVDS, digital LVDS, low-voltage back-bias, and open-drain PECL outputs. Also, the device includes an enable/disable low-power mode, a programmable holdover feature and a power-on reset.

The SL28PCIE25ALCT is intended for a wide variety of applications, including PCIe, server, storage, telecommunications, and specific automotive applications. It has been designed to offer the best performance in terms of accuracy, power efficiency, and jitter for high-performance clock-generation applications. Also, its low-power features allow the user to save energy and ensure the device offers efficient operation even in harsh ambient environments.

The chip features a pair of spread-spectrum outputs, generating low-jitter clock outputs at reduced frequencies, supporting the lowest possible power consumption. The spread-spectrum outputs reduce radiated noise, making the SL28PCIE25ALCT suitable for EMI testing as well. It also offers clock redundancy with two 156.25MHz reference clocks, allowing it to generate identical outputs.

The SL28PCIE25ALCT is widely used in many applications due to its ability to quickly and accurately generate clock signals. It is an ideal and reliable choice for applications requiring low-noise and precise clock generation. Its outputs also allow it to be used in various systems requiring highly accurate timing. The device ensures consistent performance in extreme environments and is capable of providing longer life, improved accuracy, and maximum reliability.
