DESCRIPTION
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.
