The 843023I is a Gigabit Ethernet Clock Generator and a member of the family of high performance devices from IDT. The 843023I uses a 25MHz crystal to synthesize 250MHz. The 843023I has excellent phase jitter performance, over the 1.875MHz – 20MHz integration range. The 843023I is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
