XR81112

XR81112 Universal Clock - High Frequency LVCMOS/LVDS/LVPECL Clock Synthesizer General Description The XR81112 is a family of Universal Clock synthesizer devices in a compact QFN-12 package. The devices generate ANY frequency in the range of 10 MHz to 1.5GHz by utilizing a highly flexible delta sigma modulator and a wide ranging VCO. The outputs are configurable for single ended LVCMOS or differential LVDS or LVPECL. The clock outputs have very low phase noise jitter of sub 0.6ps while consuming extremely low power. These devices can be used with standard crystals or an external system clock and can be configured to select from four different frequency multiplier settings to support a wide variety of applications. This family of products have an extremely low power PLL block with core power consumption less than 40% of equivalent devices in the market. The XR81112 is a clock synthesizer with Integer/fractional divider, LVCMOS/ LVDS/LVPECL driver, 3.3V/2.5V supply, taking a Xtal input a...
