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.

Note:

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.

PIN ASSIGNMENT

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.
