VTSS gets two buy recommendations today but its selling off major league instead of rising. Any input anyone???? JAZZ

i hadn't heard of this small-fry 'competitor' previously, bwtfdik? ----- Oki Uses GaAs Technology For Network Devices 04/13/99, 8:25 p.m. ET By Mark LaPedus, Electronic Buyers' News Saying it hopes to become a one-stop shop for components of next-generation networks, Oki Semiconductor has rolled out its latest devices for 10-gigabit-per-second bandwidth applications. Having announced its first 10-Gbps devices last year, Oki's new products for this market include a post-amplifier, automatic gain control amplifier, limiting amplifier, rectifier, and a modulator driver. Based on its gallium arsenide (GaAs) technology, Oki's parts let original equipment manufacturers develop SONET-based equipment and related products at transmission speeds of OC-192 (10-Gbps), said Moni Mathew, senior productmarketing manager for GaAs and RF products at Sunnyvale, Calif.-based Oki. Current WAN networks are being deployed at transmission speeds of OC-3 (155-Mbps), OC-12 (622-Mbps), and to some degree, OC-48 (2.5-Gbps). "Our feeling is that these transmission speeds are not sufficient to meet future bandwidth requirements," he said. "By 2000 or 2001, we believe (phone-carriers and OEMs) will deploy OC-192 networks." Oki's new devices include a post-amplifier, which has a typical gain of 14-dB and an input/output return loss of 10-dB. Maximum peak output voltage is 1.0-v, with a total power consumption of less than 1.3 W. Oki's AGC amplifier provides gain control functions. The 10-GHz part has a gain control range over 20-dB, with a power consumption of less than 1.3-W. The company's modulator driver circuit has a maximum supply current of 270 mA, an input return loss of 15-dB, and a rise and fall time of less than 40-ps. The limiting amplifier has a gain of 12-dB at 10 GHz, and a peak-to-peak amplitude of 0.8-V. Meanwhile, Oki's rectifier features a peak average power of minus 5-dB/m for an input signal of 0.8 Vpp. The devices, which are currently sampling, sell for under $2,000 per unit, in small quantities.
