Working Principle of VSC7216XUI-02

The VSC7216XUI-02 is a Multiple Protocol Clock Distribution System that utilizes a combination of synchronization and internal PLLs to control the various clocks in a transmission system. Inputs from multiple sources (crystals, resonators, networks, etc.) are divided into the system clock, peripheral clock and reference clock. These clocks are used to generate signals that can be used for frequency synthesis, phase locked loops, synchronization, etc.

The VSC7216XUI-02 also provides automatic clock synchronization and support for output frequency inversion. The device features a dual-port interface, which allows for frequency verification as well as clock tracking with bandwidth management. It also utilizes a multi-band oscillator for creating multiple frequency bands and provides low-jitter synchronization.

In addition to providing frequency reference, synchronization and clock distribution, the VSC7216XUI-02 also offers timer support for multiple events. The device supports up to four timing events as well as multi-stage phase locked loop frequency synthesis. It also has integrated oscillators to help reduce system power consumption.

In conclusion, the VSC7216XUI-02 is an advanced Multiple Protocol Clock Distribution System. It provides frequency reference, synchronization and clock distribution features, along with automatic clock synchronization and support for multiple protocol timing. It is ideal for use in consumer electronics, digital video/audio and industrial automation applications.
