Description
The FX-700 is a crystal-based frequency translator
used in communications applications where low jit-
ter is paramount.
Performance advantages include superior jitter
performance, high output frequencies and small
package size. Advanced custom ASIC technology
results in a highly robust, reliable and predictable
device. The device is packaged in a 16 pad ceram-
ic package with a hermetic seam welded lid.
