Description
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 I2C interface as well as through pins. A built-in, at-speed 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.
