PI6C39911/PI6C39912

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 135 MHz output operation

ThePI6C39911andPI6C39912offerselectablecontroloversystem

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

whiledeliveringminimalandspecifiedoutputskewsandfull-swing

logiclevels.

3.125MHzto135MHzinputoperation

(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

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.

Operation at ½ and ¼ input frequency

Operation at 2X and 4X input frequency

Zero input-to-output delay

50% duty-cycle outputs
