Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers have been embracing tremendous technological advances over the past few decades. As a result, the application field and working principle of PI6C2509-133LE, one of the clock generator ICs, have been improving as well. As a single-frequency clock generator, it is used to generate a precise high-frequency clock and a stable selectable reference clock. It is composed of a phase-locked loop (PLL) circuit and a granite digital phase-lock detector (PDPD).

PI6C2509-133LE can provide an accurate and stable clock from an input frequency up to 100MHz. The output range is from 1KHz to 133MHz, and has a step size at 1KHz. The jitter performance is also excellent since it can keep up to the requirements of IEEE 1588V2TM with the 10KHz jitter under 50pspptt. This makes it an ideal clock generator for applications such as communications, data storage, video or consumer electronics.

By utilizing its PLL circuit, PI6C2509-133LE can also achieve low power consumption and wide temperature range of -40 to +85 degree Celsius. On top of this, it utilizes the ATE-compatible granularized PDPD to curtail the spikes or drops on output signal, and generate a precise output clock with the help of an on-chip 9-bit DAC, which can offer the accuracy of 4.9 picoseconds (ps).

The working principle of PI6C2509-133LE is quite similar to that of other standard clock generator devices. The internal oscillator receives a reference clock from an external input signal, and with the help of the PDPD, it can track the changes in the reference signal. It then utilizes a built-in PLL circuit with the help of a 9-bit digital-to-analog converter (DAC), to generate a precise clock output with the required frequency.

In conclusion, PI6C2509-133LE is an excellent single-frequency clock generator IC with a wide range of application fields and a stable working principle. It provides excellent jitter performance, as well as a wide temperature range of -40 to +85 degree Celsius and low power consumption due to the efficient PLL circuit. As a result, it is an ideal choice for communications, data storage, video or consumer electronics.
