The DS92LV2411 (Serializer) and DS92LV2412 (Deserializer) chipset translates a parallel
24–bit LVCMOS data interface into a single high-speed CML serial interface with embedded clock
information. This single serial stream eliminates skew issues between clock and data, reduces
connector size and interconnect cost for transferring a 24-bit, or less, bus over FR-4 printed
circuit board backplanes, differential or coax cables.
In addition to the 24-bit data bus interface, the DS92LV2411/12 also features a 3-bit
control bus for slow speed signals. This allows implementing video and display applications with up
to 24–bits per pixel (RGB888).
Programmable transmit de-emphasis, receive equalization, on-chip scrambling and DC
balancing enables long distance transmission over lossy cables and backplanes. The DS92LV2412
automatically locks to incoming data without an external reference clock or special sync patterns,
providing easy “plug-and-go” or “hot plug” operation. EMI is minimized by the use of low voltage
differential signaling, receiver drive strength control, and spread spectrum clocking
The DS92LV2411/12 chipset is programmable though an I2C interface as well as through
Pins. A built-in AT-SPEED BIST feature validates link integrity and may be used for system
The DS92LV2411 is offered in a 48-Pin WQFN and the DS92LV2412 is offered in a 60-Pin WQFN
package. Both devices operate over the full industrial temperature range of 40°C to +85°C.
