GENERAL DESCRIPTION

The AD9551 accepts one or two reference input signals to synthesize one or two output signals. The AD9551 uses a fractional-N PLL that precisely translates the reference frequency to the desired output frequency. The input receivers and output drivers provide both single-ended and differential operation.

FEATURES

Translation between any two standard network rates

Dual reference inputs and dual clock outputs

Pin programmable for standard network rate translation
