Split Power Supplies
The VDDI pin provides the power for the INA and INB input buffers only. All the other inputs and the rest of the chip
are connected to VDDC. This allows for supply voltage translation. For example, INA and INB could be 5V clocks
(VDDI = 5V) and the rest of the chip could use a 3.3V supply on VDDC giving 3.3V output clocks. For correct
operation VDDI must always be greater than or equal to VDDC.
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the ICS580-01. These ratings, which are
standard values for IDT 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.
