ICS844101I-312 Description

The ICS844101I-312 is a low phase-noise frequency margining synthesizer and is a memHiPerClockS™ ber of the HiPerClockS™ family of high performance clock solutions from ICS. In the default mode, the device nominally generates a 312.5MHz LVDS output clock signal from a 25MHz crystal input. There is also a frequency margining mode available where the device can be programmed, using the serial interface, to vary the...
