DS92LV3241 and DS92LV3242 Serializer Deserializer

20-85MHz 32-bit channel Link II serializer and deserializer

Texas Instruments' DS92LV3241 and DS92LV3242 Serializer/DeserializerTexas Instruments' DS92LV3241 (SER) serializes a 32-bit data bus into 2 or 4 (selectable) embedded clock LVDS serial channels for a data payload rate up to 2.72 Gbps over cables such as CATx or backplanes FR-4 traces. The companion DS92LV3242 (DES) deserializes the 2 or 4 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 costs 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.
