7B991  
Programmable Skew  
Clock Buffer (PSCB)  
Logic Diagram  
FEATURES:  
DESCRIPTION:  
All output pair skew < 100 ps typical (250 max.)  
• 3.75 to 80 MHz output operation  
User-selectable output functions  
• Selectable skew to 18 ns  
Maxwell Technologies’ 7B991 Programmable Skew Clock  
Buffers (PSCB) offer user-selectable control over system  
clock functions. These multiple-output clock drivers provide  
the system integrator with functions necessary to optimize tim-  
ing 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 50while delivering minimal and specified output  
skews and full-swing logic levels.  
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)  
Zero input to output delay  
• 50% duty-cycle outputs  
• Outputs drive 50terminated lines  
Low operating current  
• Package: 32-pin RAD-PAK® flat package  
• Jitter < 200 ps peak-to-peak (< 25 ps RMS)  
• Compatible with Pentium-based processor  
Total dose hardness:  
Each output can be hardwired to one of nine delay or function  
configurations. Delay increments of 0.7 to 1.5 ns are deter-  
mined 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 transmis-  
sion line delay effects to be canceled. When this zero delay”  
capability of the PSCB is combined with the selectable output  
skew functions, the user can create output-to-output delays of  
up to ±12 time units.  
- >100 krads (Si), depending upon space mission  
• Excellent Single Event Effects:  
- SEL > 116MeV/mg/cm2  
- SEUTH -3 MeV/mg/cm2  
- SEU sat cross section: 1E-3/device  
Maxwell Technologies' patented RAD-PAK® packaging technol-  
ogy incorporates radiation shielding in the microcircuit pack-  
age. It eliminates the need for box shielding while providing  
the required radiation shielding for a lifetime in orbit or space  
mission. In a GEO orbit, RAD-PAK provides greater than 100  
krad (Si) radiation dose tolerance. This product is available  
with screening up to Class S.
