Description

The PI6C991 is a low-skew, low jitter, 5V phase-lock loop (PLL)

programmable skew clock driver, for high performance comput-

ing and networking applications. This part offers user selectable

skew-control of 4 output pairs, providing the timing delays neces-

sary 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 PI6C991 allows the REF clock input to have Spread Spectrum

modulation for EMI reduction.

The PI6C991 is pin-compatible with Cypress RoboClock CY7B991,

with improved AC/DC characteristics.
