VersaClock Software

IDT applies years of PLL optimization experience into a user friendly software that accepts the user’s target

reference clock and output frequencies and generates the lowest jitter, lowest power configuration, with

only a press of a button. The user does not need to have prior PLL experience or determine the optimal

VCO frequency to support multiple output frequencies.

VersaClock software quickly evaluates accessible VCO frequencies with available output divide values and

provides an easy to understand, bar code rating for the target output frequencies. The user may evaluate

output accuracy, performance trade-off scenarios in seconds.

Absolute Maximum Ratings

Stresses above the ratings listed below can cause permanent damage to the ICS308. 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.
