Added Figures for key parameters.
D P. Griffith 12/06/04 Changed jitter spec to +/-150 ps and duty cycle to 45% min, 55% max.
E P. Griffith 1/17/05 Renamed pin 1 to X1/CLKin on page2, improved jitter spec to +/-125 ps on front page and
in electrical tables, changed rise and fall time to 1.5 ns typical to reflect balanced drive,
changed typical ID spec to 4 ma, updated graphs on page 8 to reflect separate VDDO and
correct bypass capacitor value, updated marking diagram and ordering table to reflect
Pb-free device.
