ICS83054I-01

PRELIMINARY

The ICS83054I-01 is a 4-bit, 2:1, Single-ended Mul-

tiplexer and a member of the HiPerClockS™fam-

ily of High Performance Clock Solutions from ICS.

The ICS83054I-01 has two selectable single-ended

clock inputs and four single-ended clock outputs.

The output has a V

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 four

transceivers which need to be independently set for different

rates. For example, a board may have four 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.
