DS92LV2422SQX/NOPB

The DS92LV242x 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 reduces
interconnect cost for transferring a 24-bit or less bus
over FR-4 printed-circuit board backplanes and
balanced cables. In addition, the DS92LV242x
chipset also features a 3-bit control bus for slow
speed signals. This allows for video and display
applications with up to 24 bits per pixel (RGB).
Programmable transmit de-emphasis, receive
equalization, on-chip scrambling, and DC balancing
enables longer distance transmission over lossy
cables and backplanes. The DS92LV2422
automatically locks to incoming data without an
external reference clock or special sync patterns,
providing easy plug-and-go operation. EMI is
minimized by the use of low voltage differential
signaling, receiver drive strength control, and spread
spectrum clocking capability.
The DS92LV242x chipset is programmable though an
I
2C interface as well as through pins. A built-in, atspeed BIST feature validates link integrity and may
be used for system diagnostics. The DS92LV2421 is
offered in a 48-pin WQFN, and the DS92LV2422 is
offered in a 60-pin WQFN package. Both devices
operate over the full industrial temperature range of
–40°C to 85°C.
