DESCRIPTION
The DS92LV1023 is a 400 to 660 Mb/s serializer for
high-speed unidirectional serial data transmission
over FR-4 printed circuit board backplanes and
balanced copper cables. It transforms a 10-bit wide
parallel LVCMOS/LVTTL data bus into a single high
speed Bus LVDS serial data stream with embedded
clock. This single serial data stream simplifies PCB
design and reduces PCB cost by narrowing data
paths that in turn reduce PCB size and number of
layers. The single serial data stream also reduces
cable size, the number of connectors, and eliminates
clock-to-data and data-to-data skew.
The DS92LV1023 works well with any Texas
Instruments' Bus LVDS 10–bit deserializer within its
specified frequency operating range. It features low
power consumption, pin selectable edge trigger on
clock, and high impedance outputs in power down
mode.
The DS92LV1023 was designed with the flow-through
pinout and is available in a space saving 28–lead
SSOP package.
