General Description
The 13-bit to 26-bit ICSSTV16859 is a universal bus driver designed for 2.3V to 2.7V VDD operation and SSTL_2
I/O Levels except for the RESET# input which is LVCMOS.
Pin Configuration
Data flow from D to Q is controlled by the differential clock, CLK, CLK# and RESET#. Data is triggered on the
positive edge of CLK. CLK# must be used to maintain noise margins. RESET# must be supported with LVCMOS
levels as VREF may not be stable during power-up. RESET# is asynchronous and is intended for power-up only and
when low assures that all of the registers reset to the Low State, Q outputs are low, and all input receivers, data and
clock are switched off.
The ICSSSTV16859 supports low-power standby operation. When RESET# is LOW, the differential input receivers
are disabled, and are allowed. In addition, when RESET# is LOW, all registers are reset, and all outputs are forced
LOW. The LVCMOS RESET# input must always be held at a valid logic HIGH or LOW level.
To ensure defined outputs from the register before a stable clock has been supplied, RESET# must be held in the
LOW state during power up.
In the DDR DIMM application RESET# is specified to be completely asynchronous with respect to CK and CK#.
Therefore, no timing relationship can be guaranteed between the two. When entering RESET#, the register will be
cleared and the outputs will be driven LOW quickly, relative to the time to disable the differential input receivers,
thus ensuring no glitches on the output. However, when coming out of RESET#, the register will become active
quickly, relative to the time to enable the differential input receivers. When the data inputs are LOW, and the clock
is stable, during the time from the LOW-to-HIGH transition of RESET# until the input receivers are fully enabled, the
design must ensure that the outputs will remain LOW.
