GENERAL DESCRIPTION

The 843081I-01 is an Ethernet Clock Multiplier. The 843081I-01

accepts a crystal reference of 19.6MHz - 28MHz. The 843081I01 has excellent 1ps or lower phase jitter performance, over

the 1.875MHz - 20MHz integration range. The 843081I-01 is

packaged in a small 8-pin TSSOP, making it ideal for use in

systems with limited board space.
