ICS83056I-01

PRELIMINARY

The ICS83056I-01 is a 6-bit, 2:1, Single-ended Mul-

tiplexer and a member of the HiPerClockS™fam-

ily of High Performance Clock Solutions from ICS.

The ICS83056I-01 has two selectable single-ended

clock inputs and six 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 6 trans-

ceivers which need to be independently set for different rates.

For example, a board may have six 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 Er-

ror Correction) or non-FEC rates. The device operates up to

250MHz and is packaged in a 20 TSSOP.
