6-BIT, 2:1, SINGLE-ENDED LVCMOS MULTIPLEXER
ICS83056I-01
General Description
The ICS83056I-01 is a 6-bit, 2:1, Single-ended
LVCMOS Multiplexer and a member of the
HiPerClockS™
HiPerClockS™ family of High Performance Clock
Solutions from IDT. The ICS83056I-01 has two
selectable single-ended LVCMOS clock inputs and
six single-ended LVCMOS clock outputs. The outputs have a V
DDO
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.

NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when device
is mounted in a test socket with maintained transverse airflow greater than 500 lfpm. Device will meet specifications after thermal
equilibrium has been reached under these conditions.
NOTE 1: Measured from V
DD
/2 of the input to V
DDO
/2 of the output.
NOTE 2: Driving only one input clock.
NOTE 3: This parameter is defined according with JEDEC Standard 65.
NOTE 4: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at V
DDO
/2.
NOTE 5: Defined as skew between outputs on different devices operating at the same supply voltage and with equal load conditions.
Using the same type of inputs on each device, the outputs are measured at the differential cross points.
