SSTV16857 14-Bit Register with SSTL-2 Compatible I/O and Reset
September 2000
Revised February 2001
SSTV16857
14-Bit Register with SSTL-2 Compatible I/O and Reset
General Description
The SSTV16857 is a 14-bit register designed for use with
184 and 232 pin DDR-I memory modules. The device has
a differential input clock, SSTL-2 compatible data inputs
and a LVCMOS compatible RESET input. The device has
been designed for compliance with the JEDEC DDR mod-
ule and register specifications.
The device is fabricated on an advanced submicron CMOS
process and is designed to operate at power supplies of
less than 3.6V鈥檚.
