Cypress Semiconductor Corp CY7B992-7JI

Description
The CY7B991 and CY7B992 Programmable Skew Clock Buffers (PSCB) are multiple output clock drivers that provide user-selectable control over system clock functions. They offer:
Selectable output skew up to 18 ns
Inverted and non-inverted outputs
Operation at 12 and 14 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 500 terminated lines
Low operating current
32-pin PLCC/LCC package
Jitter < 200 ps peak-to-peak (< 25 ps RMS)

Features
All output pair skew < 100 ps typical (250 ps maximum)
3.75 MHz to 80 MHz output operation
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)
Zero input to output delay
50% duty cycle outputs
Outputs drive 500 terminated lines
Low operating current
32-pin PLCC/LCC package
Jitter < 200 ps peak-to-peak (< 25 ps RMS)

Applications
The PSCBs are ideal for use in high-performance computer systems where precise timing is critical. They can be used to:
Optimize the timing of clock signals
Reduce clock skew
Distribute clock signals over long distances
Multiply clock frequencies
Divide clock frequencies
