CY7B992  
Programmable Skew Clock Buffer  
Features  
Functional Description  
All output pair skew <100 ps typical (250 maximum)  
3.75 to 80 MHz output operation  
The CY7B991 and CY7B992 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 the timing of high perfor-  
mance 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.  
They can deliver minimal and specified output skews and full  
swing logic levels (CY7B991 TTL or CY7B992 CMOS).  
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)  
Each output is hardwired to one of the nine delay or function  
configurations. Delay increments of 0.7 to 1.5 ns are determined  
by the operating frequency with outputs that skew up to ±6 time  
units from their nominal “zero” skew position. The completely  
integrated PLL allows cancellation of external load and trans-  
mission line delay effects. When this “zero delay” capability of the  
PSCB is combined with the selectable output skew functions,  
you can create output-to-output delays of up to ±12 time units.  
Zero input to output delay  
50% duty cycle outputs  
Outputs drive 50Ω terminated lines  
Low operating current  
32-pin PLCC/LCC package  
Jitter < 200 ps peak-to-peak (< 25 ps RMS)  
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 are multiplied by  
two or four at the clock destination. This facility minimizes clock  
distribution difficulty, allowing maximum system clock speed and  
flexibility.
