843021I - Block Diagram
Description
The 843021I is a Gigabit Ethernet Clock Generator. The 84302I uses a 25MHz crystal to synthesize 125MHz. The 843021I has excellent phase jitter performance, over the 1.875MHz – 20MHz integration range. The 843021I is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
