Product Description
Pericom Semiconductor’s PI74SSTVF32852A logic circuit is
produced 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 (CK and CK). Data
registered at the crossing of CK going HIGH, and CK going LOW.
The PI74SSTVF32852A supports low-power standby operation.
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 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
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 PI74SSTVF32852A is characterized for operation from
0° to 70°C.
