IDT2308A-2DCI8

The IDT2308A-2DCI8 is a Clock/Timing IC that can be used as an adjustable frequency synthesizer and clock generator. It allows clock frequencies to be adjusted rapidly and accurately. Using a combination of phase-locked loop (PLL) and digital frequency synthesizer (DFS) technology, it is capable of generating frequencies between 10 and 350 MHz with accuracy and flexibility.

The IDT2308A-2DCI8 has several applications in the field of clock and timing, such as providing system clock functions for CPU cores and peripheral clocks, as well as being used as part of clock distribution networks. It can also be used in video processing and display applications, such as for providing precisely adjustable frequencies for a digital video signal. Additionally, in communications applications, it can be used for creating frequencies for signal and uplink receipt.

The IDT2308A-2DCI8 utilizes an on-chip PLL, which combines a phase and frequency detector, a programmable low pass filter, a voltage-controlled oscillator (VCO) and a frequency divider, all connected together in a loop. The PLL is tuned by a digitally controlled oscillator, which outputs a clock signal having a frequency that is a multiple of the external reference clock signal, allowing it to reach a wide range of frequencies. The frequency output of the IDT2308A-2DCI8 is controlled with the divider programmable register. By changing the divider value, the output frequency of the device will change accordingly.

The adjustable rising and falling edges of the output clock can also be conditioned through the programmable delay blocks, giving flexibility in optimizing the output signal. The IDT2308A-2DCI8 also includes an integrated spread spectrum frequency modulation (SFFM) module, which can be used to reduce Electromagnetic Interference (EMI) emission, allowing for efficient transmission through clock systems.

The IDT2308A-2DCI8 can work with industry-standard source and reference clock frequencies, and the power consumption is only a few hundred milliwatts. It is packaged in a 136-ball FBGA package, allowing for a low profile and allowing for easy integration into systems.

Overall, the IDT2308A-2DCI8 is a versatile clock/timing IC with many applications in the field of clock and timing, ranging from system clocks, to video processing and communications. By utilizing its adjustable frequency synthesizer and clock generation capabilities, it can provide a reliable and accurate clock signal at a wide range of frequencies. With its low power consumption and small form factor, the IDT2308A-2DCI8 is a great choice for those seeking a flexible, yet powerful clock/timing IC solution.
