The CG7476AF Clock Buffer, Driver, and Fanout device is used in a wide range of applications to provide single-ended, differential, and PECL outputs. It is particularly ideal for use in networking and telecommunications applications. It is also used in many other applications where multiple output clock signals are required.

The CG7476AF is a 3-stage buffer that provides 4-port, low-skew output port switching. It is a low-power device with a single +3.3V power supply and operates from a 3.3V supply with an option to run from a 2.5V supply. Additionally, the device features two single-ended outputs and two differential output port drivers.

The CG7476AF provides an output voltage range of 0.2V to 3.6V and is capable of driving up to four outputs at the same time. It has a maximum output current of 100mA and a peak output transient current of 250mA. The device also offers frequency range of 1GHz to 3GHz, and offers programmable fine-tuning capabilities to help ensure accurate timing of the output clock signals. Output port switching is done via a single pin.

The CG7476AF features two synchronizer modes of operation, one for a single clock edge transition and the other for two separate clock edge transitions. The device also supports a variety of logic levels, including CMOS, logic level, and LVDS. Logic levels for the outputs can be configured via registers that are accessible through the I2C interface.

The CG7476AF also offers programmable signal trace routing with automatic skew adjustment, and allows up to 8 signal traces to be routed around obstacles with up to 10 levels of signal trace manipulation available. The signal trace routing feature ensures optimized signal propagation while maintaining signal integrity.

Finally, the device also provides a low-jitter internal reference clock output and a wide voltage range of up to 10V. This allows the device to be used in a variety of applications that require reliable and accurate timing. The device also has an on-chip temperature sensor that can be used to monitor the device\'s temperature in a system.

In conclusion, the CG7476AF is an ideal device for providing single-ended, differential, and PECL outputs in a wide range of applications. It offers a wide range of features, including low-jitter clock output, programmable signal trace routing, and extensive programming capabilities. This makes it a great choice for applications requiring reliable, accurate, and low-skew clock signal distribution.
