PI6C39911A

3.3V High Speed LVTTL or Balanced Output

Programmable Skew Clock Buffer - SuperClock^®

Features

Description

• All output pair skew <100ps typical (250 Max.)

• 12.5 MHz to 133 MHz output operation

The PI6C39911A offers selectable control over system clock func-

tions. These multiple-output clock drivers provide the system

integrator with functions necessary to optimize the timing

• 3.125 MHz to 133 MHz input operation (input as low as 3.125

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

• 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

• LVTTLoutputsdrive50Ohmterminatedlines

• Operates from a single 3.3V supply

• Low operating current

• 32-pinPLCCpackage

• Jitter < 200ps peak-to-peak (< 25ps RMS)

• PI6C39911Aisapin-to-pincompatiblewithCY7B9911V

Each output can be hardwired to one of nine skews or function

configurations. Delay increments of 0.7ns to 1.5ns are determined

by the operating frequency with outputs able to skew up to ±6 time

units from their nominal “zero” skew position. The completely

integrated PLL allows external load and transmission line delay

effects to be canceled. The user can create output-to-output skew

of up to ±12 time units.

Divide-by-two and divide-by-four output functions are provided

for additional flexibility in designing complex clock systems.

WhencombinedwiththeinternalPLL,thesedividefunctionsallow

distribution of a low-frequency clock that can be multiplied by two

orfourattheclockdestination. This feature allows flexibility and

simplifies system timing distribution design for complex high-

speed systems.
