DESCRIPTION

PL580-3X

OE_CTRL

VCON

The PL580-3X is a monolithic low jitter and low

phase noise VCXO, capable of 0.4ps RMS phase

jitter and CMOS, LVDS, or PECL outputs, covering a

wide frequency output range up to 320MHz. It allows

the control of the output frequency with an input

voltage (VCON), using a low cost crystal.

The frequency selector pads of PL580-3X enable

output frequencies of (2, 4, 8, or 16) * F_XIN. The

PL580-3X is designed to address the demanding

requirements of high performance applications such

as SONET, GPS, Video, etc.

3x3 QFN

Note1: QBAR is used for single ended CMOS output.

Note2: ^ Denotes internal pull up resistor.
