1 / 6 page ![]() PL620-88/-89 Low Phase Noise XO (9.5-65MHz Output) Micrel Inc. • 2180 Fortune Drive • S an Jose, CA 95131 • USA • tel +1(408) 944-0800 • fax +1(408) 474-1000 • www.micrel.com 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 fundamental or 3rd OT crystals between 19MHz and 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.
