DESCRIPTION
:
The IDT5V991A is a high fanout 3.3V PLL based clock driver intended for high performance puting and data-munications applications. A key feature of the programmable skew is the ability of outputs to lead or lag the REF input signal. The IDT5V991A has eight programmable skew outputs in four banks of 2. Skew is controlled by 3-level input signals that may be hard-wired to...
