Rev 4/28/09 Page 1

FEATURES

 Crystal input range: 19MHz to 65MHz

 Output range: 9.5MHz – 65MHz

 Very low phase noise and jitter

 Complementary outputs:

o

LVPECL (PL620-88)

o

LVDS (PL620-89)

 Supports 2.5V or 3.3V Power Supply.

 Available in 16 pin TSSOP GREEN/RoHS

compliant package.

DESCRIPTION

The PL620-88 (LVPECL) and PL620-89 (LVDS) are

XO ICs specifically designed to work with

65MHz. The selectable divide by two feature extends

the output range from 9.5MHz to 65MHz. They

require very low current into the crystal resulting in

better overall stability.
