XR81101

Universal Clock - High Frequency LVCMOS Clock Synthesizer

Description

The XR81101 is a family of Universal Clock synthesizer devices in TSSOP-8 packages. The devices generate ANY frequency in the range of 10MHz to 200MHz by utilizing a highly flexible delta sigma modulator anda wide ranging VCO. The LVCMOS output has 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 wide variety of applications. These family of products have extremely low power PLL block with core power consumption of less 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.
