The DS92LV3221 (SER) serializes a 32-bit data bus into 2 embedded clock LVDS serial channels for a data payload rate up to 1.6 Gbps over cables such as CATx, or backplanes FR-4 traces. The companion DS92LV3222 (DES) deserializes the 2 LVDS serial data channels, de-skews channel-to-channel delay variations and converts the LVDS data stream back into a 32-bit LVCMOS parallel data bus.
On-chip data Randomization/Scrambling and DC balance encoding and selectable serializer Pre-emphasis ensure a robust, low-EMI transmission over longer, lossy cables and backplanes. The Deserializer automatically locks to incoming data without an external reference clock or special sync patterns, providing an easy “plug-and-lock” operation.
By embedding the clock in the data payload and including signal conditioning functions, the Channel-Link II SerDes devices reduce trace count, eliminate skew issues, simplify design effort and lower cable/connector cost for a wide variety of video, control and imaging applications. A built-in AT-SPEED BIST feature validates link integrity and may be used for system diagnostics.
