GigOptix’ chipset is comprised of the HXT4101A VCSEL driver and the HXR4101A multirate receiver. The chipset is designed to not only enable ultra low power consumption of less than 150mW for 100m links and 250mW for 300m links but also minimize the components required to implement a transceiver in order to reduce costs.
The HXR4101A receiver is a limiting Transimpedance Amplifier (TIA) with pre-emphasis output that eliminates the need for the post amplifier required in current industry solutions and supports multiple rates from 2Gb/s to 14Gb/s making it ideal for systems requiring backward compatibility.
The HXT4101A VCSEL driver supports up to 14Gb/s data rates while consuming less than 65mW delivering 7mA average and 7mA modulation current. The easy to use and compact designs enable applications to extend from datacom into avionic and consumer applications.
“We are very excited to introduce this new chipset solution that uniquely addresses the current and future datacom short reach needs,” stated Jörg Wieland, VP and General Manager of GigOptix- Helix, Zurich. “We developed these highly innovative products to address customer demand for high performance, lower power and better cost efficient solutions. Taking a fresh look at how we as an industry implement our transceivers, we leveraged the latest process technologies to optimize the architecture of the devices to improve performance while at the same time reducing power consumption and system cost.”
Avago Supplies First Single- Package SoC for Wireless Bluetooth 2.1 Mice
The ADNS-7630 module integrates a BT 2.1 transceiver, stand-alone baseband processor and VCSEL surface illuminator into a single package.
Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer apbplications, is marketing its ADNS- 7630 Bluetooth (BT) 2.1 LaserStream System-

on-Chip (SoC) navigation sensor for wireless mouse applications. Avago says It is the industry’s first laser navigation sensor to integrate a BT 2.1 transceiver, stand-alone baseband processor and VCSEL surface illuminator into a single package. Compared to LED-based mice, laser mice track reliably on a greater variety of smooth surfaces. The ADNS-7630 device enhances battery life - extending usage to more than 6 months from two AA battery cells - and simplifies Bluetooth mouse design, helping shorten time to market.
Avago’s LaserStream proprietary technology provides precise high-speed tracking on virtually all surfaces - a feature that is attractive to both laptop users and gaming enthusiasts. The ADNS- 7630 based mice feature high-speed motion detection of up to 30 inches per second (ips) and 8 g acceleration detection. In addition, laser power on all ADNS-7630 devices is pre-calibrated in Avago’s factory to meet IEC/EN60825-1 Class 1 Eye Safety standards, reducing assembly time and lowering cost for the manufacturer.
The ADNS-7630 device contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP), Bluetooth HID (Human Interface Device) stream output and RF transceiver. Images acquired by the IAS are processed by the DSP to determine the direction and distance of motion. The DSP generates the ∆x and ∆y relative displacement values which are then converted for wireless transmission to the Bluetooth host. All these processes are automatically executed by the ADNS-7630 without the mouse manufacturer being
