MB511
1GHz HIGH SPEED PRESCALER
HIGH SPEED PRESCALER
The Fujitsu MB511 is a 1.0GHz high speed prescaler that forms a Phase Locked
Loop (PLL) circuit when combined with a Fujitsu frequency synthesizer.Based on
Fujitsu’s advanced Bipolar processing, the MB511 maintains a consistent low
power consumption of 23mA @ 5V. In addition, it can detect low amplitude input
signals with a sensitivity of –20dBm min.
The MB511 will divide the input frequency a modulus of 1, 2, or 8, and is well
suited for applications in CATV and electronically tuned TV.

Permanent device damage may occur if the above
Absolute Maximum Ratings
are
exceeded. Functional operation should be restricted to the conditions as detailed in
the operational sections of this data sheet. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
This device contains circuitry to protect the inputs against
damage due to high static voltages or electric fields. However,
it is advised that normal precautions be taken to avoid
application of any voltage higher than maximum rated voltages
to this high impedance circuit.
