The IDT2309B-1HPGGI is a field-programmable clock generator designed for PLL and frequency synthesis applications. It features a wide range of frequency selections, including Fout of 4kHz to 400MHz, and can be programmed either from a flat configuration file or from a user-defined configuration page. It operates from a single 2.5V supply, as well as from a 3.3V or a 5V auxiliary supply. The chip has lower power consumption and better EMI than similar products. The device is ideal for applications such as PC/server server clock, system clock generation, and communication applications.

The IDT2309B-1HPGGI clock generator operates by using a dynamically controllable oscillator to generate the output frequency. It supports both single-ended and differential clock outputs. The oscillator is driven by one or more programmable current sources, which control the frequency of the output. The frequency is programmed by altering the current sources in the PLL. The device provides both on-chip programming and external programming capability, allowing the user to easily configure the parameters. It also provides a phase-locked loop (PLL) mode to improve phase noise.

The IDT2309B-1HPGGI clock generator also features an on-chip Bandwidth Selection Loop (BSL) control. The BSL allows the user to digitally program the frequency, duty cycle and phase margin of the output signal. Additionally, the on-chip spread-spectrum oscillator (SSA) can reduce EMI emissions. The SSA can be used to spread the power spectrum to reduce the peak power in the signal, which reduces EMI and improves system immunity.

In addition to these features, the IDT2309B-1HPGGI clock generator offers a variety of frequency monitoring functions. It includes a phase monitor to accurately measure the phase of the output frequency, as well as a pulse width monitor to monitor the duty cycle of the output signal. A frequency error monitor allows the user to detect and display the frequency errors over time. And lastly, a frequency monitor allows the user to measure the accuracy of the output frequency.

The IDT2309B-1HPGGI is an ideal component for PLL and frequency synthesis applications. Its low power consumption and EMI performance make it well suited for a wide range of applications, from server clocks to system clocks and communication applications. Together, these features make this component ideal for applications that require frequency accuracy and precision.
