Harris Semiconductor Announces 12- and 14-bit DACs in its CommLink Family of Communication Ics

— New converters couple high performance with pin compatibility

SAN JOSE, CA, Wireless Symposium ‘99, February 23, 1999 – Harris Semiconductor today unveiled its highest performance D/A converters yet within its CommLink Family of Communication ICs. The HI5860 (12-bit single), HI5828 (12-bit dual) and HI5960 (14-bit single) are specifically designed for the transmit section of communications systems.

While targeting communications manufacturers, these devices are particularly well-suited for wireless applications such as wireless local loop, cellular basestations and I & Q modems. They feature excellent spurious-free dynamic range (86 dBc @ 100MSPS) for quality signal synthesis, offer high speeds up to 125MSPS, and can provide over 70dBc of dynamic range while generating 8 carriers (6-10MHz @ 64MSPS). This is extremely important in cellular applications where dynamic range sets the system-level performance.

In addition, Harris’ 12- and 14-bit DACs achieve low power consumption of 175mW at 5V (35mW at 3V) while operating from a single 3-volt or 5-volt supply. They provide a maximum of 20mA of full-scale output current coupled with low glitch energy and excellent frequency domain performance. The HI5828’s dual channel design offers a higher level of integration to the system designer, thus optimizing board space and channel matching without sacrificing performance.

The HI5860 and HI5960 are now in full production. The HI5860 and HI5960 are packaged in small, 28-lead SOICs, while the HI5828 (dual) is available in a 48-lead TQFP package.

The CommLink D/A product offering features 8-, 10-, 12- and 14-bit pin compatibility and 60 and 125MSPS update rates, thus providing a variety of price/performance options. For higher speed versions (165MSPS) contact Harris for availability. For information, please visit the Harris Semiconductor website at http://www.semi.harris.com.

The CommLink family is an example of Harris Semiconductor's commitment to high-speed signal processing as applied to communication applications. Harris’ CommLink D/A family covers the resolution scale from 8- to 14-bits and up to 165 MSPS. In addition to data converters, Harris addresses the entire signal processing chain with a portfolio of linear, mixed-signal and DSP ICs optimized for high-speed communications products.
