Description
Electromagnetic interference (EMI), which is due to
electromagnetic radiation emitted from an external
source, is an unwanted disturbance in an electrical
circuit. In general, EMI is generated when the clock
oscillator outputs a high-frequency signal. To reduce
EMI, various components need to be added to the
board, increasing the time and resources to complete
design and measurement.
The Fujitsu Spread Spectrum Clock Generator (SSCG)
reduces radiated EMI that results from system clock
operation. It minimizes the need for other shielding
components like bypass capacitors, choke coil and
ferrite bead, resulting in system-level cost savings.

Digital Method
•
Digital frequency modulation technique
−Digital control using a current D/A converter
achieves accurate frequency modulation compared
to conventional analog control, which causes
distortion and blunting in the modulated
waveform
•
•
Selectable modulation rate
−No modulation, ± ±.ꢀ5, ± 1.±5, ± ꢁ.±5, -1.±5,
-ꢁ.±5, -4.±5
Enhanced input frequency range
−8.3MHz to 134MHz
•
•
Low current consumption
−ꢀ.ꢀmA @ ꢁꢀMHz

•
•
Programmable product (built-in FRAM)
−Set and save output frequency and modulation
parameters by changing the multiplication /
division clock rate
−1.6ꢀ V to 3.6 V
•
•
Pin compatibility with other products in the market
Single input and multiple outputs (Max. 8 Clock
outputs, Example: MB88181)
−One device supports multiple clocks, thus reducing
the need for other components such as oscillators
