Detailed Description
The DS1181L modulates an input clock to generate a
center-dithered spread-spectrum output. A 20MHz to
134MHz clock is applied to the CLKIN pin. An internal
PLL dithers the output clock about its center frequency
at a user-selectable magnitude.
Spread-Spectrum Dither Magnitude
The DS1181L can generate dither magnitudes up to
±2%. The desired magnitude is selected using input pins
SMSEL1 and SMSEL2 as shown in Table 1.
Spread-Spectrum Dither Rate
The output spread-spectrum dither rate is fixed at
fIN/832.

SSEN
Spread-Spectrum Enable. Three-level input to enable/disable spread-spectrum and to three-state the output.
0 = Power-up/spread-spectrum enabled.
Float = SSO three-stated.
1 = Power-up/spread-spectrum disabled (not a bypass mode).

SSO
Spread-Spectrum Clock Output. Outputs a center-dithered spread-spectrum version of the clock input at
CLKIN.
Clock Range and Dither Rate Select. Three-level input that determines the dither rate. See the Detailed
Description section for details.
