IDT5T9820NLI

IDT5T9820NLI is a multi-section, high-performance frequency synthesizer designed to provide the highest levels of performance while meeting the requirements of next-generation digital circuits. This device is suitable for use in a variety of applications, from networking, communications, computing, and multimedia to encryption, storage, and telepresence.

The IDT5T9820NLI is an integrated circuit (IC) containing a clock generator, phase-locked loop (PLL), and frequency synthesizer. The device can synthesize frequencies from 300 kHz up to 3.2 GHz with a single reference input. The PLL output is connected directly to an output divider to provide the desired frequency using a single 10-bit programming clock input. The PLL is designed to achieve low jitter and wide locking range, enabling the device to work over a variety of input reference frequencies.

IDT5T9820NLI is a valuable solution for system designers looking to minimize power consumption in their designs. The device boasts a low power consumption of only 16mA, with a standby current of 0.63mA. This makes it ideal for use in small, low-power applications such as cellular phones, embedded systems, and digital home appliances.

The working principle of IDT5T9820NLI involves a free-running oscillator and a phase-frequency detector (PFD). The free-running oscillator generates an output signal known as the reference signal. The PFD uses this signal to compare with the input signal to the device and adjusts the synthesizer divider value to regenerate a signal at the desired output frequency. The PFD can also detect when the input signal is no longer present and will revert back to the original reference signal.

The IDT5T9820NLI is a versatile device which finds utility in a wide range of applications. It can be used in communications systems to generate local oscillator signals, network clocks, and reference clocks. In multimedia systems, the device can generate oscillator signals for modulators, receivers, and transmitters. The device is also suitable for use in storage systems, encryption systems, and telepresence applications.

In conclusion, the IDT5T9820NLI is a highly versatile frequency synthesizer which is suitable for a wide range of applications. Thanks to its low power consumption, the device is ideal for use in mobile and embedded systems. The device offers fast settling times, low jitter, and wide locking ranges, making it a valuable solution for system designers.
