A clock generator, Phase Locked Loop (PLL) or frequency synthesizer is an electronic circuit used to generate a signal with an accurate frequency. The ASM3I2669AF-06OR is a member of this class of devices and is based on a VCO (Voltage Controlled Oscillator) architecture that combines a wide frequency tuning range and excellent accuracy and phase noise performance.

At the heart of the ASM3I2669AF-06OR is a VCO coupled with a programmable divider and a phase detector. The VCO generates a fundamental frequency of reference which is then divided down to a lower frequency by the programmable divider. This lower frequency is then compared to an external reference frequency by the phase detector. The phase detector outputs a frequency error signal which is used to adjust the frequency of the VCO. The process is repeated at a set frequency until a steady-state frequency is achieved between the output of the VCO and the external reference frequency.

In terms of application field, the ASM3I2669AF-06OR is ideal for use in wired and wireless communication systems, such as cellular base stations, WiFi and WiMAX infrastructure, and clock and frequency control applications in high-speed circuits. Its excellent phase noise performance of -93.2dBc/Hz@1kHz offsets makes it ideal for a wide range of edge-of-network applications such as clock synchronization, jitter attenuation, and frequency pull-in range extension.

The device can also be used in high-speed clock data recovery applications, such as PLL frequency tracking phase aligners and Ethernet Rx clocks. The high accuracy and outstanding phase noise of the clock source makes this device particularly suited for packet-level clock and data recovery, enabling reduced power consumption and improved bit error ratio (BER) performance.

The ASM3I2669AF-06OR is a highly customizable clock source, with an adjustable tuning range of 5MHz to 2400MHz. It is able to generate a number of signals, including clock output (CLK), symmetry clock output (SCLK), clock enable (EN), and clock recovered from data output (CRD). Additionally, it offers comprehensive monitoring and diagnostics capabilities, with a wide range of diagnostic signal outputs and monitor pins for accurate signal locking status and determination.

In summary, the ASM3I2669AF-06OR is a highly configurable, low-power clock generator/synthesizer capable of producing highly accurate and low-phase-noise clock signals. It is ideal for a wide range of clock and frequency control applications and is particularly suited for applications requiring low-noise clock and data recovery and synchronization. The device is suitable for use in wired and wireless communication systems, as well as clock and frequency control applications in high-speed circuits or edge-of-network applications.
