FEATURES
Spread Spectrum Clock Generator with selectable
multiplier from 1x to 6x outputs.
Output frequency ranges: 10MHz to 180MHz.
Accepts input from crystal or reference clock.
Selectable Center, Down or Asymmetric Spread
Modulation.
Selectable Modulation rate.
TTL/CMOS compatible outputs.
3.3V Operating Voltage.

Available in 8-Pin 150mil SOIC.
DESCRIPTION
The ABE0101/02/04/06 are Spread Spectrum Clock
Generators 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
from a crystal or reference clock input and provides
1x to 6x modulated clock outputs.
PIN CONFIGURATION
Note:
^: Internal pull-up resistor (120k
for SD, 30 k for
SC0-SC2).
*: The value of SD is latched upon power-up. The
internal pull-up resistor results in a default high value
when no pull-down resistor is connected to this pin
(recommended external pull-down resistor of 27 k
).
