Vishay Siliconix Releases New 20-V and 30-VP-Channel Power MOSFETs With Industry’s Lowest On-ResistanceThe devices will be used as the adaptor switch and for load switching applications in notebook computers and industrial/general systems. Adaptor switches (switching between the adaptor/wall power and the battery power) are always on and drawing current. The lower on-resistance of the Si7135DP and Si7633DP translates into lower power consumption, saving power and prolonging battery life between charges. [Read more...] |

The growing use of the Internet has created increasingly higher demand for multi-Gbps I/O performance. The demand for 100 Gbps+ WAN bandwidth fuels the growth of short-reach 40 Gbps infrastructures within high-end telco and datacom routers, switches, servers and other proprietary chassis-to-chassis links.
The Zarlink PX5419A 12X3 Gbps VCSEL Driver* with ACJTAG is a twelve-channel VCSEL driver designed for various 12x3 Gbps parallel PMD applications. It consists of a DC-coupled amplifier with selectable modulation and bias currents optimized for driving commercially available, common cathode VCSELs from a single +3.3 V supply.
Individual channel settings are used to control the modulation and bias current and their temperature coefficients, allowing the optical output power and extinction ratio to be optimized. Data controlling the Primarion PX5419A VCSEL Driver settings is loaded by a simple four-wire CMOS serial interface that features read/write capabilities.
The Primarion PX5419A Driver provides full ACJTAG support for boundary scan testability, allowing either AC or DC module connectivity validation and systems test.
