NATIONAL SEMICONDUCTOR ANNOUNCES 40MHZ DATA DESERIALIZER THAT ENABLES HOT BOARD SWAPPING IN GROWING DATA AND TELECOMMUNICATIONS APPLICATIONS

DS92LV1212 Receiver Completes Chip Set That Is Half the Cost and Consumes Half the Power Of Competitive Devices

September 7, 1999 - National Semiconductor® Corporation (NYSE:NSM) today announced the 40MHz DS92LV1212 receiver deserializer that converts serial streams into 10-bit data for wide-band CDMA, cellular base station, Ethernet, TDMA and central-office switch applications. It also is designed for video and imaging applications, such as TV studio equipment and MRI medical imaging systems.

"With its companion DS92LV1021 10-bit transmitter serializer, the DS92LV1212 offers designers a flexible chip set that is half the cost of competitive solutions and consumes only 400mW because of its CMOS design, half the power of competing devices," said Eric King, marketing manager for National's Interface group. "In addition, the chip set permits hot swapping, allowing users to insert new communications cards into live serial data streams without disrupting information flow or turning off power, and its bus LVDS (low voltage differential signaling) technology enables one device to drive many receivers, increasing performance and lowering chip count."

The DS92LV1212 is the latest National bus LVDS product designed to speed the integration of data, voice and video traffic as systems move from 10Mbs to 100Mbs and higher bandwidth transmission. Other key features include a frequency range of 16- to 40MHz, data rate of 400Mbs and 120ps jitter peak to peak.

CMOS technology not only gives the DS92LV1212 the lowest power consumption of any serial data rate device on the market, but also provides other cost and system benefits. Power-saving CMOS translates to less heat dissipation than with competing devices manufactured using BiCMOS or gallium arsenide processes. Consequently, the chip set requires less thermal management, thus reducing system complexity, board area and space requirements.

Pricing and Availability
Available now, the DS92LV1212 is priced at $9.50 each (1000-unit quantities) in a 28-pin SSOP package. With the DS92LV1021, also in a 28-pin SSOP package, the chip set is priced at $19.00 in 1000-unit quantities. An evaluation kit containing a transmitter board, a receiver board and a mini backplane can be ordered as part number BLVDS02.
