The CY25811SXI is a dual-output monolithic frequency synthesizer that is capable of generating two frequency outputs ranging from frequent 100 Hz to 1 MHz. It is used in applications such as clock and timing synthesis and spectrum analyzers, digital systems, telecommunications, system automation and distributed clock systems. The CY25811SXI cuts through the complexities of frequency synthesizers in order to allow customers to quickly integrate the device into their systems.

The CY25811SXI utilizes a sigma-delta architecture with a low-lag phase detector to ensure low-power consumption and fast frequency tracking. It supports both selectable and programmable-phase-lock loops (PLLs). The output reference frequencies can be modulated over a frequency range of up to 160-kHz in order to support high-performance applications.

The CY25811SXI is also able to generate high-performance differential output signals. It relies on its internal oscillator, which is accurate within 5 parts per million (PPM), and can be looped back to any available output frequency. It also allows for an automated acquisition of lock status using its “Acquire” feature.

The CY25811SXI is the ideal choice for applications with demanding jitter requirements. It contains a primary PLL with a low-noise synthesizer, which enables the device to generate frequencies with low-jitter performance. It also features an integrated low-noise preamplifier, allowing for improved dynamic range and wide-bandwidth operation.

In addition, the CY25811SXI provides a programmable-voltage generator (PVG) option that a user can enable to provide an adjustable voltage for controlling voltage-controlled oscillators (VCOs) and timing components. It supports both single-ended and differential outputs, as well as external triggers for resynchronization of the PLL.

The CY25811SXI is a highly versatile, low-power frequency synthesizer that provides superior performance in applications requiring low-jitter performance. It is fully integrated and offered in a wide range of power ratings. The device also features a wide operating temperature range and is compatible with a variety of operating systems, making it an ideal choice for a wide range of applications.
