RTC clock synchronization buffer driver delay chip

The NB3N5573 is a high precision, low phase noise clock generator that supports PCI Express and Ethernet requirements. Part of the PureEdge product family, this device accepts a 25 MHz fundamental mode parallel resonant crystal and generates differential HCSL outputs clocked at 25 MHz, 100 MHz, 125 MHz, or 200 MHz. The device is available in a narrow 5.0 mm x 4.4 mm TSSOP 16-pin package.
