data sheet sept. 1995 edition 4.0a mb505 -16 ultra high frequency prescaler ultra high frequency prescaler the fujitsu mb505 is a high frequency, up to 1.6ghz, prescaler used with a frequency synthesizer to form a phase locked loop (pll). it will divide the input frequency by the modulus of 128 or 256 and the output level is 1.6v peak to peak on ecl level. operation in the 1.6ghz range meets the specification for applications in direct broadcasting satellite systems (dbs), catv systems, and uhf transceivers. features high frequency operation 1.6ghz max. low power dissipation 45mw typ. wide operation temperature -40 c to +85 c stable output amplitude v out = 1.6v pp complete pll synthesizer circuit with the fujitsu MB87006A, pll synthesizer ic plastic 8-pin standard dual-in-line package or flat package absolute maximum ratings (see note) rating symbol value unit supply voltage v cc 0.5 to +7.0 v input voltage v in 0.5 to v cc v output current i o 10 ma storage temperature t stg 55 to +125 c 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. plastic package fpt-08p-m01 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. plastic package dip-08p-m01 in v cc sw out in nc gnd nc 1 2 3 45 6 7 top view 8
