... DIV Device Operation The ICS581-01 and ICS581-02 are very similar. Following is a description of the operation of the ICS581-01 and the differences of the ICS581-02. The ICS581- PLL-based, zero delay, clock multiplexer. The device consists of an input multiplexer controlled by SELA that selects between two clock inputs. ...

... A typical application for the ICS581- provide a backup clock for a system. The backup reliable clock would be connected to INB while the main clock would be connected to INA. If the main clock failed, the ICS581-02 would automatically be switched to the backup clock. The following example shows the connection for this. ...

... ZERO DELAY GLITCH-FREE CLOCK MULTIPLEXER External Components The ICS581-01 and ICS581-02 require two 0.01µF capacitors between VDD and GND, one on each side of the chip. These must be close to the chip to minimize lead inductance. Series termination resistors of 33Ω should be used on the outputs, should also be close to the chip, and the feedback path should be a direct connection from a clock output to a FBIN pin, routed directly under the chip to minimize trace length ...
