IDT5T9316NLGI8 is one of the clock buffers, drivers, and timing ICs (Integrated Circuits) that are made by Integrated Device Technology (IDT.). It is a general purpose Clock & Data Fractional Spread Spectrum Buffer with integrated logic to prepare fractional spread-spectrum outputs that can be used to reduce electro-magnetic interference (EMI). It is a type of self-contained, small circuit component that works as a data transmitter or receiver, allowing multiple pieces of circuit equipment to communicate with each other and allowing uninterrupted operation. IDT5T9316NLGI8 offers an effective way to enhance system performance while controlling power levels, by providing an extended frequency range and a reduced operating temperature.

IDT5T9316NLGI8 advantages include its on-chip EMI reduction, the ability to support all leading clock and data rates, minimize ratio templates for applications up to 4GHz, and the ability to provide output clock, data, and spread-spectrum signals from three independent pins. It provides a typical jitter of a few picoseconds and a typical additive of 45ps peak-to-peak jitter for <4GHz data rates. IDT5T9316NLGI8 is available in an 8-pad TQFN Package with a standard 2.5V Output Voltage. Operating voltage range is between 2.3V and 3.3V. It has a wide frequency range of up to 4GHz chip-to-chip data rate. It is fabricated using low-power silicon technology.

The IDT5T9316NLGI8 has a number of programmable features to accommodate a wide variety of system clock designs, such as frequency output limits, part-to-part symmetry, and spread-spectrum spread amount. It also has an integrated logic block that provides a logic level-shifting function, allowing the use of different logic levels for the clock and data outputs. The IDT5T9316NLGI8 is able to program the spread-spectrum rate, enable/disable fractional rate division, and provide the clock output to different frequencies without reprogramming the device.

In applications where the system clock rate is changing over time, the IDT5T9316NLGI8 includes optional low-power fractional–n frequency synthesis to compensate for changes in clock speed. Additionally, the integrated logic block supports frequency synthesis to be configured as an up or down slicer, allowing the device to be used as a clock frequency de-scalar or scalar.

IDT5T9316NLGI8 is commonly applied in automotive systems, handheld devices, communications systems, high-end GPU, and other industries including military, aerospace, and energy. It is a useful component in extending battery life as well as increasing system performance, especially in low-power applications. Furthermore, it provides immunity to environmental noise and is suitable for EMI sensitive applications such as handheld devices and automotive electronics.

The working principle of the IDT5T9316NLGI8 can be summed up as follows: it is a low-power fractional-spread clock generator with a fractional-n frequency synthesis capability. The IC takes multiple input clock, data, and spread-spectrum signals, and generates two spread-spectrum output clocks and two spread-spectrum data signals. This enables the generation of Spread Spectrum signals with very low power consumption and minimal jitter. Additionally, the integrated logic block supports frequency synthesis to be configured as an up- or down-slicer, allowing the device to be used as a clock frequency de-scalar or scalar.
