The ICS83056I-01 is a 6-bit, 2:1, Single-ended Multiplexer and a member of the HiPerClockSTMfamHiPerClockSTM 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 applications. 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 transceivers 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 Error Correction) or non-FEC rates. The device operates up to 250MHz and is packaged in a 20 TSSOP.
