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.

Description: The LV32EVK01 is an easy to use evaluation kit for the DS92LV3221, DS92LV3222, DS92LV3241 and DS92LV3242 Channel Link II Serializers and Deserializers. This kit allows for the evaluation of high speed data links ranging from 640 Mbps to 2.72 Gbps over low cost cables. The transmitter board accepts 32 bits of LVCMOS data signals from an incoming data source along with the clock signal. The serializer converts the LVCMOS parallel lines into four serialized CML data pairs with an embedded clock. Additional encoding, including data randomization, DC- Balancing and bit shuffling, allow the serializer to connect to the deserializer through AC-coupled interfaces. The receiver board accepts the CML serialized data streams with embedded clock and converts the data back into parallel LVCMOS data signals and clock. The embedded clock allows the deserializer to lock onto the incoming data without the need for a reference clock or oscillator. The deserializer also features an integrated deskew circuit which allows the device to compensate for large amounts of cable skew in the serial interconnect.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
