ICS558-01
PECL/CMOS TO CMOS CLOCK DIVIDER
External Components
The ICS558-01 requires two 0.01 µF capacitors between VDDP and GND, and VDDC and GND—one on
each side of the chip. These must be close to the chip to minimize lead inductance. Series termination
resistors of 33Ω can be used on the outputs (these also must be close to the chip).
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the ICS558-01. These ratings,
which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of
the device at these or any other conditions above those indicated in the operational sections of the
specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can
affect product reliability. Electrical parameters are guaranteed only over the recommended operating
temperature range.
