PI6C9911 & PI6C9911E

5V High-Speed Programmable Skew

Clock Buffers - SuperClock

Product Features

Description

• Four pairs of programmable skew outputs

• User-selectable output functions:

− Selectable skews

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.

− 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

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.

• 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)

Both buffers are pin-compatable with Cypresss RoboClock

CY7B9911, but with improvedAC/DC characteristics.

The PI6C9911 and PI6C9911E also have the same pinout as

Cypresss CY7B9911and with balanced output drive.

• Output Operation

3.75 to 100 MHz for PI6C9911

3.75 to 125 MHz for PI6C9911E
