SerDes Chipset First to Integrate Zero-Latency Control Channel

The Channel Link III serializer and deserializer (SerDes) family is allegedly the industry’s first to integrate a zero-latency, bidirectional control channel. The devices deliver clock, high-speed data and a low-speed, bidirectional I2C control bus over a single twisted wire pair, significantly reducing interconnect size, weight, and cost by up to 50% for industrial video, imaging, and display apps. The family includes two chipsets: the DS92LX2121 serializer and DS92LX2122 deserializer, which drive 18-bit color display apps or data links up to 1,050 Mb/s, and the DS92LX1621 serializer and DS92LX1622 deserializer, which drive 16-bit data up to 800 Mb/s. Both chipsets use a CMOS (LVCMOS) parallel interface and operate from 10 MHz to 50 MHz. Prices range from $5.10 to $5.30 each/1,000. NATIONAL SEMICONDUCTOR CORP., Santa Clara, CA. (800) 272-9959.
