Description
The PI6C39911 and PI6C39912 offer selectable control over system clock functions. These multiple-output clock drivers provide the system integrator with functions necessary to optimize the timing of high-performance computer systems. Eight individual drivers, arranged as four pairs of user-controllable outputs, can each drive terminated transmission lines with impedances as low as 50 ohms while delivering minimal and specified output skews and full-swing logic levels.

FEATUREs
• All output pair skew <100ps typical (250 Max.)
• 12.5 MHz to 135 MHz output operation
• 3.125 MHz to 135 MHz input operation (input as low as 3.125 MHz for 4x operation, or 6.25 MHz for 2x operation)
• User-selectable output functions
    - Selectable skew to 18ns
    - Inverted and non-inverted
    - Operation at ½ and ¼ input frequency
    - Operation at 2X and 4X input frequency
• Zero input-to-output delay
• 50% duty-cycle outputs
• LVTTL outputs drive 50-ohm terminated lines
