DESCRIPTION

The DS92LV0411 (serializer) and DS92LV0412

(deserializer) chipset translates a Channel Link LVDS

video interface (4 LVDS Data + LVDS Clock) into a

high-speed serialized interface over a single CML

pair.

The DS92LV0411/DS92LV0412 enables applications

that currently use the popular Channel Link or

Channel Link style devices to seamlessly upgrade to

an embedded clock interface to reduce interconnect

cost or ease design challenges. The parallel LVDS interface also reduces FPGA I/O pins, board trace

count and alleviates EMI issues, when compared to

traditional single-ended wide bus interfaces.

Programmable transmit de-emphasis, receive

equalization, on-chip scrambling and DC balancing

enables longer distance transmission over lossy

cables and backplanes. The Deserializer

automatically locks to incoming data without an

external reference clock or special sync patterns,

providing easy “plug-and-go” operation.

The DS92LV0411 and DS92LV0412 are

programmable though an I2C interface as well as by

pins. A built-in AT-SPEED BIST feature validates link

integrity and may be used for system diagnostics.

The DS92LV0411 and DS92LV0412 can be used

interchangeably with the DS92LV2411 or

DS92LV2412. This allows designers the flexibility to

connect to the host device and receiving devices with

different interface types, LVDS or LVCMOS.
