Description

   The ICS83840AHLF is a DDR SDRAM MUX and is a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The device 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 application: 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 ICS83840AHLF ideal for demanding applications which require well defined performance and repeatability.
