WESTLAKE VILLAGE, Calif. -- Inphi Corporation, a privately held electronic components company, today announced two optical modulator drivers for SONET OC-192 and SDH STM-64 fiber optic network systems. Capable of driving a variety of differential Mach-Zehnder modulators, the new 1311DZ and 2011DZ provide network ultra equipment manufacturers with a robust, cost-effective solution for metro, long haul, and long haul telecommunications markets and for broadband instrumentation and automated test equipment (ATE) applications. The 1311DZ supports non-return-to-zero (NRZ) data rates up to 12.5 gigabits per second (Gbps), while the 2011DZ supports NRZ data rates up to 20 Gbps or return-to-zero (RZ) data rates up to 12.5 Gbps for maximum versatility. Both devices exhibit superior edge rates and excellent eye quality, as depicted in the eye diagrams in Figure 1, making them ideal for high-bit-rate transmission systems. Low jitter (less than 0.5 picoseconds rms) and fast rise and fall times (less than 18 picoseconds) help ensure high-quality signal output. Power consumption is held to a minimum, with each device dissipating less than 1.9 watts at an output level of 6 volts differential peak to peak. "With the addition of the 1311DZ and 2011DZ to our product portfolio, Inphi now offers the most comprehensive line of drivers available," said Gary Franzosa, director of marketing at Inphi. "Customers have told us that Inphi's broad selection of high-performance parts affords them increased flexibility when building transponder modules for different market segments. The combination of high bandwidth, low power dissipation, and an extremely small form factor design make the 1311DZ and 2011DZ ideal for the performance demands of today's networking systems."
