Fujitsu Microelectronics Brings Latest Wireless System-on-Chip Technology to Annual Wireless Symposium

New SAW filters, digital-to-analog converters, PLLs ready for next generation of cellular, PDA, handheld products

San Jose, CA, February 13, 2001 — Fujitsu Microelectronics, Inc. (FMI) will showcase its new digital-to-analog converter (DAC) devices, surface acoustic wave (SAW) filters and ultra-small phase locked loop (PLL) ICs, along with its new Fast Cycle RAM (FCRAMÔ), at the annual Wireless Portable Symposium and Exhibition (Booth 429). FMI also will demonstrate JPEG decoding using an ARM-7TDMI through USB transfer, a part of the company's comprehensive System-on-Chip platform.

New DACs Developed for Base Stations, Antennas, Satellites
The company's new MB86061 is a CMOS digital-to-analog converter that provides high-speed, high-resolution conversion capabilities for communications base stations, advanced antenna systems, test equipment, satellite uplinks and ultra-high-resolution imaging systems. The DAC provides a 12-bit 400MSa/s sampling rate with compatible emitter coupled logic (ECL) I/Os, delivering overall system performance typical of Bipolar/BiCMOS devices. The latest in Fujitsu's growing family of DACs, the MB86061 provides superior spectral performance using its proprietary segment shuffling, which averages errors caused by manufacturing variations of the core quadrants. Pricing starts at $48 each in 1,000-piece units.

SAW Filters for W-CDMA Applications
The new SAW filters are designed for high-frequency 1.95 GHz and 2.14 GHz wideband CDMA applications. Based on lithium tantalate (LiTaO3), the SAW filter family uses a "ladder" design that combines serial and parallel on-chip resonators to provide an insertion loss of less than 3.5dB, along with high stop-band attenuation. The SAWs, members of the Fujitsu F6 series, support low inductance and high resistance to shock, mechanical vibration and climate changes. Impedance is just 50 Ohms, so designers do not need to include external matching circuits. The SAWs are available in 3 x 3 millimeter and 2.5 x 2.0 millimeter surface mount packages that are less than one millimeter in height. Each SAW filter has one input and one output pin; the balanced Rx filter has just one input pin and two balanced output pins, allowing the filter to be connected directly to a mixer input. Pricing begins at $1.80 in 10,000-unit quantities.

UL Series of PLLs
Fujitsu's UL series of BiCMOS PLLs, which is now available for the cell phone market, support various standards such as W-CDMA, GSM/DCS and PDC. Each member of the UL series optimizes the power-consumption level of mobile phones with operating frequencies from 50Hz to 2.6GHz. For example, the MB15F78UL consumes only 4.5mA at 2.7 volts and provides a lock-up time that is 20 percent less than previous models in Fujitsu's PLL family. A second member of the series requires between 2.5mA and 3.2mA. Pricing in 1,000-unit volumes starts at $2 each.
"Fujitsu is very focused on providing total wireless solutions. We are now the industry leader in SAW filters and PLLs, and our new digital-to-analog converters provide superior performance in a wide range of communications applications," said Keith Horn, marketing director of FMI's Systems Solutions Group. "As the industry moves to the next generation of cellular and handset technology, these ICs provide the high reliability, small footprint and overall value that designers require."

New FCRAMs for Cell Phones, Handsets
Another key product for the wireless market is the company's Fast Cycle RAM, designed for next-generation mobile phone applications including Internet access, music distribution and e-mail. The new family of 16 Mbit high-density RAMs features wide-range power-supply voltages of 2.3V to 2.7V, and of 2.7V to 3.1V, with 16-bit I/O organization. Samples in 48-pin FBGA packages are available now at $20 each.

JPEG Decoding on ARM-7 through USB Illustrates Fujitsu's Wireless SOC Technology
Fujitsu has also developed a complete semiconductor solution for wireless applications. A demonstration of JPEG decoding using an ARM-7TDMI through USB transfer illustrates an element of Fujitsu's SOC development platform.
