描述 Description

The PI6C3Q99X family is a high fanout 3.3V PLL-based clock driver intended for high performance computing and data-communications applications. A key feature of the programmable skew is the ability of outputs to lead or lag the REF input signal. The PI6C3Q991 has 8 programmable skew outputs in 4 banks of 2, while the PI6C3Q993 has 6 programmable skew outputs and 2 zero skew outputs. Skew is controlled by 3-level input signals that may be hardwired to appropriate HIGH-MID-LOW levels.
