PI6C3991

3.3V High-Speed, Low-Voltage

Programmable Skew Clock Buffer

SuperClock

Features

Description

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

• 3.75 MHz to 80 MHz output operation

• User-selectable output functions

— Selectable skew to 18ns

PI6C3991 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-perfor-

mancecomputersystems.Eightindividualdrivers,arrangedasfour

pairs of user-controllable outputs, can each drive terminated trans-

mission lines with impedances as low as 50 ohms while delivering

minimal and specified output skews and full-swing logic levels

(LVTTL).

— Inverted and Non-Inverted

— Operation at ½ and ¼ input frequency

— Operation at 2X and 4X input frequency

(input as low as 3.75 MHz, x4 operation)

• Zero input-to-output delay

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

up to ±12 time units.

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

foradditionalflexibilityindesigningcomplexclocksystems.When

combined with the internal PLL, these divide functions allow

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

two or four at the clock destination. This feature allows flexibility

and simplifies system timing distribution design for complex

high-speed systems.

• 50% duty-cycle outputs

• LVTTLoutputsdrive50-ohmterminatedlines

• Operates from a single 3.3V supply

• Low operating current

• Availablein32-pinPLCC(J)package

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