Mom-and-pop operationsSo who is selling the biggest chunk of China's electronic components? The answer is that there are roughly 1,800 electronic-component distributors selling parts in mainland China. Most of those companies are exclusively focused on China, but many of them hail from Taiwan, Hong Kong and Singapore and have representative offices in China.

The ARM RealView Development Suite 3.0 is available now. ARM Partners upgrading from RVDS 2.2 with valid support and maintenance contracts are entitled to a 30 percent discount, the company said. Specific pricing information was not provided.

Norwood, Mass. — Analog Devices Inc. expanded its clock and data recovery (CDR) offering with four chips that tout outstanding jitter performance to simplify optical network designs.

For designers of datacom and telecom applications, the CDRs simplify system design by exceeding synchronous optical network (Sonet) jitter specifications in all categories (jitter transfer, jitter generation and jitter tolerance) by more than a factor of three, the company said.

The ADN2817 and ADN2818 CDRs for networking applications are said to consume up to 25 percent less power and offer more features than ADI's previous CDR generation.

In addition, ADI is introducing two ultra low-power, fixed-rate ICs that are pin-compatible with its continuous tuning CDRs — and are optimized to minimize the cost and complexity of implementing broadband passive optical network (BPON), according to ADI.

The ADN2817 (650 milliwatts) and ADN2818 (600 mW) are low-power extensions of ADI's family of pin-compatible continuous-tuning CDRs for fixed-rate, multi-rate and continuous-tuning data communications and telecom applications. The ICs are capable of recovering continuous data at rates from 10 megabits per second to 2.7 gigabits per second without external control or the use of a reference clock &#151 making these devices optimal for wave-division multiplexing (WDM) systems that require protocol agnostic capability.

The ADN2817 and ADN2818 offer up to a 1.5-dB improvement in optical sensitivity over ADI's previous generation CDR. Via an I2C interface, optional features such as double data rate (DDR) can be accessed.

The ADN2804 and ADN2806 are fixed-rate CDRs that deliver the low power, features and data rates to exceed BPON requirements. The devices automatically lock to a 612-Mbits/s input data stream without the use of a reference clock or external control. Additionally, in the absence of input data, the devices are able to maintain an accurate output clock. The ADN2804 includes an on-chip limiting amp and dissipates 423 mW, while the ADN2806 has no limiting amp and dissipates only 359 mW.

All four CDRs are packaged in 5 x 5-mm LFCSPs. The ADN2817 and ADN2818 are sampling now with production quantities planned for August 2006, and are respectively priced at $43.74 and $41.55 each in 1,000-piece quantities. Click here for the ADN2817 and ADN2818 data sheets.

« Ce changement stratégique permettra de renforcer notre positionnement en tant que fournisseur de systèmes pour le secteur automobile et nous donnera un véritable élan dans l’électronique automobile », a commenté Manfred Wennemer, président de Continental, dans un communiqué.

La transaction devrait être finalisée au cours du premier semestre 2006.

Milpitas, Calif. — Intersil Corp.'s operational amplifier features an 8-MHz low-pass filter that is said to remove Global System for Mobile Communications (GSM) noise from the video band — and it also serves as an anti-aliasing filter.

The ISL59111 op amp/video driver comes in a 1 x 1.5-mm chip scale package (CSP) and integrates an operational amplifier, filter and sync-tip clamp onto a single, compact device. It is guaranteed to a 0.7-mm maximum height constraint and specified for operation from -40°C to +85°C.

Input is sensed below the ground rail so the device can see the negative sync pulse of a video signal better than any competitive device now available,” said Kathryn Tucker, marketing manager for Intersil's video product group. This new single supply video driver is very highly integrated. The filter removes GSM burst noise while the sync-tip clamp positions the video signals so they will move through the amplifier smoothly,” she said.
