illustrate
The DS92LV3221 (SERVICE) serializes 32-bit data data into 2 embedded clocks for LVDS serial channels with a data payload rate that exceeds the traces of FR-4 cables such as CA, or backplane FR-4 cables to 1.6 Gbps buses. The deserialized 2 LVDS serial data channels of the DS92LV3222 (DES) de-skew the channel-to-channel delay changes and convert them into 32-bit parallel data bus LVCMOS LVDS data streams back.
On-chip data randomization/scrambling and DC-balanced coding and optional serial pre-emphasis ensure a robust, low-EMI transmission of long, lossy cables and backplanes. The deserializer autolock eliminates the need for an external reference clock synchronization mode or special incoming data, providing a simple "plug-and-lock" operation.
By embedding in the data payload, including clock signal conditioning functions, the channel second loop count SerDes device reduces tracking, eliminates offset issues, simplifies design effort, and reduces the cost of various connectors for wire/one video, control, and imaging applications. The built-in verification of link integrity in the AT high-speed BIST feature can be used to perform system diagnostics.
