DESCRIPTION (continued)

The SCD558XA is designed to work with the Serial port of most

common microprocessors. The Clock I/O (CLK I/O) and Clock

Select (CLKSEL) pins offer the user the capability to supply a

high speed external clock. This feature can minimize audio band

interference for portable communication equipment or eliminate

the visual synchronization effects found in high vibration environ-

ments such as avionics equipment.
