FEATURES
DESCRIPTIONS
The PLL701-01/02/04/06 is a Spread Spectrum Clock
Generator designed for the purpose of reducing EMI
in high-speed digital systems. Any output frequency
from 10 to 180MHz can be selected by programming
6 multiplier modes. The device is designed to operate
over a very wide range of input frequencies and
provides 1x to 6x modulated clock outputs.
OUTPUT CLOCK (FOUT) SELECTION
Notes: C: Center Spread. A: Asymmetric Spread. D: Down Spread.

... Selection is made by connecting specific pins to a logical “zero” or “one”, according to the output clock selection table and modulation rate selection table on page 1. In order to reduce the number of pins on the chip, the PLL701-01/02/04/06 uses pin 2 (XOUT/SD bi- directional pin. The pin serves as modulation rate selector input (SD) upon power-up (see modulation rate table on page 1), and as XOUT crystal connection as soon as the input has been latched ...
