ICS83052I-01

PRELIMINARY Integrated Circuit Systems, Inc. ICS83052I-01 2-BIT, 2:1, SINGLE-ENDED MULTIPLEXER GENERAL DESCRIPTION The ICS83052I-01 is a 2-bit, 2:1, Single-ended Multiplexer and a member of the HiPerClockS™famHiPerClockS™ 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 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 www.DataSheet4U.com 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.
