ALLENTOWN, Pa.-Lucent Technologies Inc.’s Microelectronics Group introduced a subscriber line interface circuit chip that operates on 3.3 volts of power, thereby reducing power consumption by about 35 percent compared with 5-volt SLICs.
The SLIC chip, called the L9215, is targeted for use by telephone companies in short-distance subscriber loops, such as fixed-wireless local loop and intelligent network terminals. The SLIC provides the power and the ringing signals to the telephone line and passes the voice signals to the codec, where the signals are converted from analog to digital and digital to analog, said Lucent.
“Our wireless local loop and Internet access provider customers need 3.3-volt SLICs because they want to squeeze every penny out of the costs of their solutions,” said Randy Pitts, analog line card product manager with Lucent’s Microelectronics Group. “To date, SLICs have been the only components left in their solutions that still run off of 5 volts as well.”
The L2915 comes in a 32-pin plastic leaded chip carrier. Samples will be available in August, with production quantities by year-end. They are priced at $4 for quantities of 10,000.
