LVDS chip set delivers gigabit output

Based on low-voltage differential-signaling technology, the DS90C387 programmable transmitter and the DS90CF388 falling-edge receiver display-interface chips for flat-panel monitors can maintain a throughput of 5.38 Gbits/s. The chips, which are connected over 10 m of cable between the GUI display controller on the desktop and the timing-control ASIC on the LCD, can support resolutions from SVGA (800 x 600 pixels) through UXGA (1600 x 1200 pixels), and higher. Housed in 100-lead TQFP packages, they use a 354-mV swing to reduce noise levels and can be used as a 3-V dual-pixel configuration performing at 224 MHz. The `C387 and `CF388 cost $10.75 and $11.25, respectively, in quantities of 1000. National Semiconductor Corp., 2900 Semiconductor Dr., Santa Clara, CA 95052; (800) 272-9959; Fax: (408) 739-9803.
