MB88155
■ SPECTRUM EXAMPLE CHARACTERISTICS
The condition of the examples of the characteristic is shown as follows : Input frequency = 16 MHz (Output
frequency = 64 MHz : Using MB88155-410 (Multiplied by 4) )
Power-supply voltage = 3.3 V, None load capacity. Modulation rate = ± 1.0% (center spread).
Spectrum analyzer HP4396B is connected with CKOUT. The result of the measurement with RBW = 1 kHz (ATT
use for −6 dB) .
