General Description

The 840001-34 is a two output LVCMOS/LVTTL Synthesizer. One

output is the LVCMOS/LVTTL main synthesized clock output (Q)

and one output is a three-state LVCMOS/LVTTL reference clock

(REF_OUT) output at the frequency of the crystal oscillator. The

device can accept crystals from 15.3125MHz to 42.67MHz and

can synthesize outputs from 81.67MHz to 213.33MHz. The

840001-34 is packaged in a 3mm x 3mm 16-pin VFQFN, making it

ideal for use on space constrained boards.
