Overview

The 843022I-02 is a Gigabit Ethernet Clock Generator. The 843022I-02 uses a 25MHz crystal to synthesize 125MHz or 62.5MHz. The 843022I-02 has excellent phase jitter performance, over the 12kHz – 20MHz integration range. The 843022I-02 is packaged in a small 16-pin VFQFN, making it ideal for use in systems with limited board space.
