PI6C9911 & PI6C9911E
5V High-Speed Programmable Skew
Clock Buffers -
SuperClock™
Product Features
Four pairs of programmable skew outputs
User-selectable output functions:
Selectable skews
Inverted and noninverted
Operation at ½ and ¼ input frequency
Operation at 2X and 4X input frequency
Low skew <100ps typical same pair, 250ps max.
Allow REF clock input to have Spread Spectrum
modulation for EMI reduction
2X, 4X, ½ and ¼ outputs
3-level inputs for skew and output frequency control
External feedback, internal loop filter
Low cycle-to-cycle Jitter: <25ps RMS
Duty cycle of output clock signals: 45% min. 55% max.
Same pinout as Cypress CY7B9911
Available in 32-pin PLCC Package (J)
Output Operation
3.75 to 100 MHz for PI6C9911
3.75 to 125 MHz for PI6C9911E
Description
The PI6C9911 and PI6C9911E are low-skew, low jitter, 5V phase-
lock-loop (PLL) programmable skew clock drivers, for
high-performance computing and networking applications. These
parts offer user-selectable skew-control of 4 output pairs, provid-
ing the timing delays necessary to optimize high-performance
clock-distribution circuits.
Each output can be hardwired to one of nine delay or function
configurations. Delay increments are determined by the input clock
frequency and the configurations selected by the user.
The PI6C9911 and PI6C9911E allow the REF clock input to have
Spread Spectrum modulation for EMI reduction.
Both buffers are pin-compatable with Cypress’s RoboClock
CY7B9911, but with improved AC/DC characteristics.
The PI6C9911 and PI6C9911E also have the same pinout as
Cypress’s CY7B9911and with balanced output drive.
