April 23, 2001 - National Semiconductor Corporation (NYSE: NSM) announced today at the NAB 2001 Conference, the CLC030, a Serial Digital Video (SDV) Encoder that serializes parallel data stream at data rates compatible with both SMPTE 259M (Standard Definition) and SMPTE 292M (High Definition) digital video signals. The CLC030 provides manufacturers of professional video equipment a solution that, at 500mW offers a 70 percent lower power dissipation than competing products, resulting in greater reliability, longer battery life in battery-powered applications, and lower cost.
Designed to support the interface requirements of professional (broadcast) video equipment, the CLC030 takes a parallel data input (10 bits for Standard Definition Video, 20 bits for High Definition Video) does scrambling and encoding per the Society of Motion Picture and Television Engineers (SMPTE) standards, and provides a serial output data stream. The standard interface used in such equipment is SMPTE 259M for standard definition video signals, and SMPTE 292M for high definition video signals. The CLC030 will support both standards, allowing it to become a truly universal interface circuit. Additional functions include the ability to insert ancillary data (ANC) packets into the stream via a low speed FIFO interface.
The CLC030 complements National's SDV chipset, which includes a cable driver, cable equalization, data retiming, decoding, and crosspoint switch functions. The chipset enables a point-to-point interface, supporting a 400 Mb/s data link over a distance of 300m.
"With Standard Definition and High Definition interfaces integrated into a single chip, designers of broadcast equipment will have more flexibility as they develop their products," said Mark Sauerwald, technical marketing manager at National. "While enjoying the added functionality afforded by National's CLC030 in Standard Definition applications, an added bonus comes as they update the design to High Definition -- it will be like getting High Definition for 'free'."
National Semiconductor is featuring a demonstration of the CLC030 at their booth #L117 at NAB 2001 in Las Vegas this week.
Pricing and Availability
Available in mid-May and packaged in a 64-pin PQFP, the CLC030 is priced at $50.00 each when purchased in quantities of 1,000.
