Repeaters Double Performance At Half Power

The latest multi-channel PowerWise 10-Gb/s repeaters provide an equalization gain of 36 dB while consuming half 55 mW/channel, and operate over 20 meters of 24-AWG cable. The DS100BR410 includes four unidirectional channels and consumes 55 mW/channel while supporting a 2.5V supply. It extends interconnect reach by performing both receive equalization and transmit de-emphasis on each of its channels. The DS100BR210 with two unidirectional channels and the DS100BR111 with one bidirectional lane consume 65 mW/channel and support 3.3V/2.5V supplies. Both devices perform receive equalization up to 36 dB gain and transmit de-emphasis of -12 dB. All three repeaters allow powering down of unused channels and apply signal conditioning settings via pin setting or SMBus. Prices for the DS100BR410, DS100BR210, and DS100BR111 are $13, $6.95, and $6.95 each/1,000. NATIONAL SEMICONDUCTOR CORP., Santa Clara, CA. (800) 272-9959.
