TriQuint’s TQ1090 is a configurable clock buffer which generates 11 outputs, operating over a wide range of frequencies from 33 MHz to 45MHz, 65 MHz to 90 MHz and 130 MHz to 180 MHz. The outputs are available at 1x, 2x and 4x, or at 1/2x, 1x and 2x, or at 1/4 x, 1/2 x and 1x the reference clock frequency, fREF.

Features
