The XR81102 is a family of Universal Clock synthesizer devices in TSSOP-8 packages. The devices generate ANY frequency in the range of 100 MHz to 700MHz by utilizing a highly flexible delta sigma modulatorand a wide ranging VCO. The high clock frequency LVPECL outputs have very low phase noise jitter of sub 150fs, while consuming extremely low power. These devices can be used with standard crystals or external system clock to support a variety of applications. This family of products have an extremely low power PLL block with core power consumption less than 40% of the equivalent devices from competition. By second sourcing several of the existing sockets, these devices provides a very compelling power efficiency value benefit across all market segments.
