Focus on precision timing challenges Product News 4/29/2004 Post a comment Electronic clock devices are not your grandfather's chime clock; no, the clocks used in today's electronics are much more precise and versatile. Electronic clocks are the quarterback of the PCB team that determine the rhythm and accuracy of the signals getting passed around and off the board.
CDMA power amplifiers deliver on integration, performance, price Product News 4/21/2004 Post a comment SiGe Semiconductor announced the industry's first commercially viable silicon-based CDMA power amplifiers. Leveraging a highly efficient silicon germanium BiCMOS process, the three power amplifiers achieve performance parity with GaAs-based devices, while delivering the integration, manufacturing and price benefits of silicon.
Cygnal fabs single-chip USB to UART bridge Product News 4/12/2004 Post a comment Mixed-signal chip maker Cygnal now has available a power-managed USB-to-UART bridge chip. It provides USB v2.0 full speed-to-921-kbaud UART data transfers, thanks to separate 512 byte Transmit and Receive buffers. The IC can be self-powered or USB bus powered, and can quickly update legacy UART, RS-232, and RS485 systems with USB connectivity.
NAS On-a-Chip Product News 4/12/2004 Post a comment Complete Network Attached Storage System-on-a-Chip (NASoC). Solution Enables Simple Installation, Storage Expansion, Data Backup and Redundancy for Residential and Small Business Users.
Active Upconverting Mixer Integrates RF Transformer Product News 4/12/2004 Post a comment Two new high linearity upconverting RF active mixers with integrated RF transformers from Linear Technology provide the right combination of distortion, local oscillator drive requirement, port-to-port isolation, and conversion loss for RF designs.
Ideal diode offers increased efficiency for automatic switching Product News 4/12/2004 Post a comment Linear Technology Corporation introduces the LTC4412HV, an ideal diode controller with at least 10x lower forward voltage than a Schottky diode. As a result, the device provides increased efficiency by an order of magnitude in systems requiring load sharing or automatic switching between DC input power sources.
Boost Controller consumes only 120 micro amps at no load Product News 4/1/2004 Post a comment Microchip introduces a series of 750-kHz gated oscillator DC/DC Boost Controllers. These devices can deliver 5 Watts of power to the load while consuming only 120 microamps of quiescent current at no load. They are used to generate the supply voltage for microcontrollers and other electronic loads from a battery supply or the bus voltages available in the system.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
