ProductDescription
PericomSemiconductor’sPI74SSTVF16859logiccircuitisproduced
using the Company’s advanced sub-micron CMOS technology,
achieving industry leading speed.
All inputs are compatible with the JEDEC standard for SSTL_2,
except the LVCMOS reset (RESET) input. All outputs are SSTL_2,
Class II compatible.
The device operates from a differential clock (CLK and CLK). Data
registeredatthecrossingofCLKgoingHIGH,andCLKgoingLOW.
ThePI74SSTVF16859supportslow-powerstandbyoperation.When
RESET is LOW, the differential input receivers are disabled, and
undriven (floating) data, clock and reference voltage (VREF) inputs
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 CLK and CLK. 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
comingoutof RESET,theregisterwillbecomeactivequickly,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
remainLOW.
Pericom’s PI74SSTVF16859 is characterized for operation from
0°Cto70°C.
