IDT5V50009DCG is a Clock/Timing – Clock Generators, PLLs, Frequency Synthesizers device. It is a programmable low-skew pin frequencies divider with low jitter, intended to simplify device synchronization tasks. This integrated circuit features a high-speed multiply-by/divide-by and adjustable clock PLLs buffered by a multiple output drivers. The device features low jitter inputs and low jitter outputs, as well as wide range of frequency division ratios.

The IDT5V50009DCG chip integrates two 6-input, 1-output PLLs, programmable division ratios and a wide range of output drivers. It uses high impedance differential inputs, allowing for high division ratio (up to 32x or 1/32x). The device is available in various packages, such as QFN, BGA, and TQFP. Programmability is accomplished through serial programming.

The device can be used to provide either high-resolution or low-jitter clock sources. It is frequently used to divide a master clock with a low clock-frequency and low dead-time to simultaneously multiple lower speed clocks for synchronous operation. The IDT5V50009DCG device is often used as part of a clock tree network to ensure that the designed logic can enter synchronous operation without glitches or jitter generated transitioning between clocks.

In its most basic configuration, the IDT5V50009DCG clock generator can be used to divide a clock frequency provided by the user’s design. The input clock entries are then multiplied or divided to generate the appropriate output clocks. The divider output clocks can be instantaneously changed with no dead-time or glitch artifacts. This allows for greater flexibility in the end-design.

The device also provides a wide range of output drivers, which increases the possible design variations. The output frequency output can also be changed in real-time, meaning that the outputs can be adjusted to accommodate different frequency requirements or events. Furthermore, the device can be programmed through an I2C serial interface.

In summary, the IDT5V50009DCG is a versatile programmable device which can be used to provide low jitter clock sources, or to enable the synchronization of multiple lower speed clocks in a wide variety of applications. Its high resolution divide ratio, low jitter output and I2C serial programmability make it a suitable choice for applications such as Gb/s serial links, telecom backplanes and clock distribution systems.
