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
• Programmable product (built-in FRAM)
−Set and save output frequency and modulation
parameters by changing the multiplication /
division clock rate
• 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
• Selectable modulation rate
−No modulation, ±0.5%, ±1.0%, ±2.0%, -1.0%,
-2.0%, -4.0%
• Enhanced input frequency range
−8.3MHz to 134MHz
• Low current consumption
−5.5mA @ 25MHz
• Power supply voltage range
−1.65 V to 3.6 V
• Pin compatibility with other products in the market
• Package options
−SOP8, TSSOP8, BCC6, BCC18, BCC20
