描述 Description

The 840001I-34 is a two output LVCMOS/LVTTL Synthesizer and a member of the family of high performance devices from IDT. 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 840001I-34 is packaged in a 3mm x 3mm 16-pin VFQFN, making it ideal for use on space constrained boards.
