ESCRIPTION
The 844021-01 is an Ethernet Clock Generator. The 844021-01
uses an 18pF parallel resonant crystal over the range of 24.5MHz
– 34MHz. For Ethernet applications, a 25MHz crystal is used. The
844021-01 has excellent <1ps phase jitter performance, over the
1.875MHz – 20MHz integration range. The 844021-01 is packaged
in a small 8-pin TSSOP, making it ideal for use in systems with
limited board space.
