Date Description of Change
10/07/04 Changed the input frequency from 14.31818 to 25 MHz; changed Short Circuit Current
from ±70 to ±50; added separate Pull-up resistor spec for SS_EN; added “I” to part
ordering number
11/15/04
12/06/04
Changed AC and DC parameters to reflect measured char values: I_DD, I_DDO, V_IH, V_IL,
R_PU, I_I, R_PD, t₁,.t₂, t₃, t₄, t_ja, t_EN, t_DIS, t_P. Added Figures for key parameters.
Changed jitter spec to +/-150 ps and duty cycle to 45% min, 55% max.
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.
