2-BIT, 2:1,
SINGLE-ENDED MULTIPLEXER
GENERAL DESCRIPTION
The ICS83052I-01 is a 2-bit, 2:1, Single-ended Mul-
ICS
tiplexer and a member of the HiPerClockS™fam-
HiPerClockS™ _{ily of High Performance Clock Solutions from ICS.}
The ICS83052I-01 has two selectable single-ended
clock inputs and two single-ended clock outputs.
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 translation ap-
plications. An output enable pin places the output in
a high impedance state which may be useful for testing or
debug. Possible applications include systems with up to two
transceivers which need to be independently set for different
rates. For example, a board may have two transceivers, each
of which need to be independently configured for 1 Gigabit
Ethernet or 1 Gigabit Fibre Channel rates. Another possible
application may require the ports to be independently set for
FEC (Forward Error Correction) or non-FEC rates. The device
operates up to 250MHz and is packaged in a 16 TSSOP.
