ESCRIPTION
The ICS83840B is a DDR SDRAM MUX and is
a member of the HiPerClockS family of High
Performance Clock Solutions from ICS. The de-
vice has 10 Host Lines and each host line can
be passed to 4 Data Ports. The 10 channels are
allocated as follows in the DDR SDRAM appli-
cation: 8 data lines, 1 strobe line and 1 DQm line. The Host/
Data Ports are compatible with single-ended SSTL-2 and the
device operates from a 2.5V supply.
Guaranteed low output skew makes the ICS83840B ideal
for demanding applications which require well defined per-
formance and repeatability.
