MB501L/504/504L
TWO MODULUS PRESCALERS
TWO MODULUS PRESCALERS
The Fujitsu MB501L/504/504L are two modulus prescalers, which are use with
a frequency synthesizer to make a PLL (Phase Locked Loop). They will divide
the input frequency by the modulus of 64/65 or 128/129 for the MB501L, and
32/33 or 64/65 for the MB504/MB504L. The MB501L and MB504L are
low-power versions. The output of 1.6V peak to peak on ECL level applies to all.
High Operating Frequency, Low Power Operation:
1.1GHz at 50mW typ. (MB501L)
520MHz at 50mW typ. (MB504)

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. 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.
