The ICS83056I-01 is a 6-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 ICS83056I-01 has two selectable single-ended
clock inputs and six single-ended clock outputs.
The output has a VDDO 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
www.DataSheeat4Uh.igcohmimpedance 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.
