Description
The PI6C39911 offers 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 133 MHz output operation
• 3.125 MHz to 133 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
• Inputs are 5V Tolerant
• LVTTL outputs drive 50-Ohm terminated lines
• Operates from a single 3.3V supply
• Low operating current
• 32-pin PLCC package
• Jitter < 200ps peak-to-peak (< 25ps RMS)
