Crystal-to-3.3V, 2.5V
LVPECL 400MHz Frequency Synthesizer
ICS843801I-24
DATA SHEET
General Description
The ICS843801I-24 is a 400MHz Frequency Synthesizer. The
ICS843801I-24 uses an 18pF parallel resonant crystal over the
range of 21.5625MHz - 25.3125MHz. The ICS843801I-24 has
excellent <1ps phase jitter performance, over the 12kHz - 20MHz
integration range. The ICS843801I-24 is packaged in a small 8-pin
TSSOP, making it ideal for use in systems with limited board space.
Features
One differential 3.3V, 2.5V LVPECL output
