Description

The ICS581-02 is a glitch free, Phase Locked Loop (PLL) based clock multiplexers (mux) with zero delay from input to output. This device has four low skew outputs which can be configured as a single output, three outputs, or four outputs. The ICS581-02 has automatic switching between the two clock inputs. The ICS581-02 is a member of IDT’s ClockBlocksTM family of clock generation, synchronization, and distribution devices.
