DESCRIPTION
The PL580-30 is a monolithic low jitter and low phase noise VCXO, capable of 0.4ps RMS phase jitter and PECL, LVDS, or CMOS outputs, covering a wide frequency output range up to 640MHz. It allows the control of the output frequency with an input voltage (VCON), using a low cost crystal. The PL580-30 is designed to address the demanding requirements of high performance applications such as SONET, GPS, XDSL, etc.
