20 BIT, DDR SDRAM 2:1 MUX
GENERAL DESCRIPTION
The ICS83841 is a 20 Bit, DDR SDRAM 2:1 MUX
ICS and is a member of the HiPerClockS™family of
HiPerClockS™ High Performance Clock Solutions from ICS. The
device has 20 host lines and each host line can
be passed to 2 data ports. The host/data ports
are compatible with single-ended SSTL-2 and the device op-
erates from a 2.5V supply.
www.DataSheeGt4uUa.craomnteed low output skew makes the ICS83841 ideal for
demanding applications which require well defined performance
and repeatability.
FEATURES
Forty low skew single-ended DIMM ports
One SSTL-2 compatible select input
Maximum Switching Speed: 3ns
Output skew: 180ps (maximum)
ron = 20Ω (typical)
Full 2.5V supply modes
0°C to 70°C ambient operating temperature
Available in both standard and lead-free RoHS compliant
packages
