GENERAL DESCRIPTION

The 843031I-01 is an 10Gb Ethernet Clock Generator. The

843031I-01 uses an 18pF parallel resonant crystal. The 843031I-01

has excellent <1ps phase jitter performance, over the 1.875MHz -

20MHz integration range. The 843031I-01 is packaged in a small

8-pin TSSOP, making it ideal for use in systems with limited board

space.
