The PI6C20800BIAE is a high-performance clock synthesizer dedicated to communication interface applications. This device integrates low-power differential PECL/LVPECL oscillator and differential CML output buffer, which can create many clock configurations with a minimum of external components.

The application field of the PI6C20800BIAE is mainly in the telecom equipment field, and it is widely used in access networking, mobile core networking and backbone networking. It can provide edges to the communication systems of operators, which can greatly improve the accuracy and performance of the network.

The working principle of the PI6C20800BIAE is based on Frequency Synthesis. It is a mixed-signal device that combines a digital PLL and voltage-controlled oscillator. The device generates multiple low-noise differential PECL/LVPECL/CML clock signals with low jitter. It integrates a low-power differential PECL/LVPECL oscillator and a differential CML output buffer section, allowing the device to configure multiple frequencies with minimal external components. The device can also generate Low-Voltage PECL/LVPECL, Low Voltage Differential Signaling, and CML clock output signals. It can be used to generate high-quality clock signals for networking ICs, optical modules, and many other communication-related applications.

The PI6C20800BIAE provides programmable frequency output up to 4GHz. It also features high-speed PLL bandwidth with adjustable pull-in and lock range. With one supply voltage, the device is capable of providing up to four outputs with the same frequency, while the other four output frequency could be tuned differently. Through PLL parameters like loop filter, reference divider, and VCO divider, the user can easily configure desired frequency output. The device supports frequency spread spectrum, which can reduce EMC effect in applications requiring frequency hopping.

In addition, the PI6C20800BIAE also supports adjustable power saving mode. It only powers up the used outputs for reducing power consumption. The outputs can be powered on/off electronically depending on customer-required application. The device also provides output power on delay, which can be used to reduce additional ringing on the output.

The PI6C20800BIAE has some advanced features like startup guard band and spread-spectrum noise cancellation. The startup guard band can prevent any false triggering of the output at start-up and reduce jitter peaks during output configuration. The spread-spectrum noise cancellation minimizes the Non-Phase Lock Loop (NPLL) noise during spread-spectrum operation mode.

In conclusion, the PI6C20800BIAE is a high-performance clock synthesizer dedicated to communication interface applications such as network ICs, optical modules, and many others, greatly improving the accuracy and performance of the network. It is also easy to configure and set, with adjustable power saving modes and spread-spectrum noise cancellation.
