DESCRIPTION
The DS92LV1224 is a 300 to 660 Mb/s deserializer
for high-speed unidirectional serial data transmission
over FR-4 printed circuit board backplanes and
balanced copper cables. It receives the Bus LVDS
serial data stream from a compatible 10–bit serializer,
transforms it back into a 10-bit wide parallel data bus
and recovers parallel 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 DS92LV1224 works well with Bus LVDS 10–bit
serializers within its specified frequency operating
range. It features low power consumption, and high
impedance outputs in power down mode.
The DS92LV1224 was designed with the flow-through
pinout and is available in a space saving 28–lead
SSOP package.
