The following chip is not recommended for new designs but if its for a home
project it should be OK. See the following URL for the data sheet.

There may also be newer versions available if you ask the manufacture.

Hello,

I'm looking for a prescaler reference with a ratio of 64 and 128, able
to operate up to 3GHz.

I had in mind to use the Motorola MC12079 (64/128, 2.8GHz) but it's
discontinued. The fujitsu MB506 (64/128, 2.4GHz) is difficult to find.

Have you some other part numbers to suggest ?

Many thanks

Stephane, F1TJJ
