functions. These multiple-output clock drivers provide the sys-  
tem integrator with functions necessary to optimize the timing  
Features  
• 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  
of high-performance computer systems. Eight individual driv-  
ers, 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 (LVTTL).  
— Inverted and non-inverted  
— Operation at 12 and 14 input frequency  
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 zeroskew position. The com-  
pletely integrated PLL allows external load and transmission line  
delay effects to be canceled. When this zero delaycapability of the  
LVPSCB is combined with the selectable output skew functions, the  
user can create output-to-output delays of up to ±12 time units.  
— Operation at 2x and 4x input frequency (input as low  
as 3.75 MHz)  
• Zero input to output delay  
• 50% duty-cycle outputs  
LVTTL Outputs drive 50terminated lines  
Operates from a single 3.3V supply  
Low operating current  
Divide-by-two and divide-by-four output functions are provided  
for additional flexibility in designing complex clock systems.  
When combined with the internal PLL, these divide functions  
allow distribution of a low-frequency clock that can be multi-  
plied by two or four at the clock destination. This facility mini-  
mizes clock distribution difficulty while allowing maximum sys-  
tem clock speed and flexibility.
