Exar Corporation XRT8010
The XRT8010 is a monolithic analog phase locked loop that provides a high frequency LVDS clock output, using a low frequency crystal or reference clock. It is designed for SONET/SDH and other low jitter applications.The high performance of the IC provides a very low jitter LVDS clock output up to 320 MHz, while operating at 3.3 volts. The XRT8010 has a selectable 8x or 16x internal multiplier for an external crystal or signal source.| Part No. | XRT8010 |
