Modified LDO regulator sinks PECL-termination current Design How-To 6/28/2005 Post a comment For high-speed clock and data systems, positive emitter-coupled-logic (PECL) - a differential signaling scheme - is emerging as a preferred alternative to single-ended CMOS and TTL logic. High-speed ECL offers differential I/O, with excellent skew and jitter control, along with fast rise and fall times. From the June issue of Planet Analog magazine, a Maxim engineer shows how to extract high current.
Single-chip, triple differential receiver reduces board space by more than half Product News 6/28/2005 Post a comment Analog Devices Inc.' AD8143 is a compact, single-chip solution that receives differential signals over a twisted pair cable. The triple differential receiver is primarily designed to receive RGB (red, green, blue) signals with resolutions up to 1600 X 1200; however, it can able be used to receive any other type of differential analog signal or high-speed data transmission.
Enhanced host bridge supports dual-processor systems Product News 6/24/2005 Post a comment Tundra Semiconductor is concentrating its efforts on producing host bridges that support PowerPC processor-based designs. The company just released a derivative of its Tsi108 system controller that supports dual processors and offers better power management capabilities than its counterpart.

Die GIFT-Zertifizierung garantiert einen hohen Grad an Kompatibilität – wichtige Voraussetzung bei vielen Automotive-Designs.
MCU and networking chipset module target ZigBee apps Product News 6/17/2005 Post a comment Texas Instruments has teamed-up with Ember Corp. to launch a microcontroller and networking chipset module for the ZigBee wireless sensing and control market. TI provides its MSP430F161x series of microcontrollers while Ember provides its EM2420 802.15.4/ZigBee-compliant semiconductor platform.
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
