DESCRIPTION
The STLVD210 is a low skew programmable
1-to-5 dual differential LV DS drive r, designed with
clock distribution in mind. The LVDS input signals
can be either differential or single-ended if the
VBB output is used.
The STLV D210 is provided with a 11 bit shift
register with a serial in and a Control Register.
The purpose is to enable or power off each output
clock channel and to select the clock input . The
STLVD210 is s pec ific ally designed, modelled and
produced with low s ke w as the key goal. Optimal
design and layout serve to minimize gate to gate
skew within a device. The net result is a
dependable guaranteed low skew dev ice.
The STLVD210 can be used for high performanc e
clock distribution in 2.5V systems wi th LVDS
levels. Designers can be take advantage of the
device’s performance to d istribute low skew
clocks across the backplane or the board.
