描述

The 843023 is a Gigabit Ethernet clock generator that uses a 25MHz crystal to synthesize 250MHz. The 843023 has excellent phase jitter performance, over the 1.875MHz – 20MHz integration range. The 843023 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
