CY7B991V  
3.3V RoboClock®  
Low Voltage Programmable Skew Clock Buffer  
Features  
Functional Description  
All output pair skew <100 ps typical (250 max)  
3.75 to 80 MHz output operation  
The CY7B991V Low voltage Programmable Skew Clock Buffer  
(LVPSCB) offers user selectable control over system clock  
functions. These multiple output clock drivers provide the system  
integrator with functions necessary to optimize the timing of  
high-performance computer systems. Each of the eight  
individual drivers, arranged in four pairs of user controllable  
outputs can drive terminated transmission lines with impedances  
as low as 50Ω. This delivers minimal and specified output skews and  
User selectable output functions  
Selectable skew to 18 ns  
Inverted and non-inverted  
Operation at 12 and 14 input frequency  
Operation at 2x and 4x input frequency (input as low as 3.75  
MHz)  
full swing logic levels (LVTTL).  
Each output is hardwired to one of nine delay or function config-  
urations. Delay increments of 0.7 to 1.5 ns 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. When this “zero delay” capability 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.  
Zero input to output delay  
50% duty cycle outputs  
LVTTL outputs drive 50Ω terminated lines  
Operates from a single 3.3V supply  
Low operating current  
32-pin PLCC package  
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  
enable distribution of a low frequency clock that is multiplied by  
two or four at the clock destination. This facility minimizes clock  
distribution difficulty allowing maximum system clock speed and  
flexibility.
