ESCRIPTION
The ICS83052I is a low skew, 2:1, Single-ended
Multiplexer and a member of the HiPerClockS™
HiPerClockS™
family of High Performance Clock Solutions from
ICS. The ICS83052I has two selectable single-
ended clock inputs and one single-ended clock
output. The output has a V
DDO
pin which may be set at 3.3V,
2.5V, or 1.8V, making the device ideal for use in voltage trans-
lation applications. An output enable pin places the output
in a high impedance state which may be useful for testing
or debug. The device operates up to 250MHz and is pack-
aged in an 8 TSSOP.
