Ultra-low-power MOSFETs prolong battery life
Intersil has launched its advanced new DenseTrench power MOSFET family of discrete power devices designed for higher-efficiency low-voltage power switching applications.
Programmable up-converter simplifies basestations
Intersil has added a new highly integrated quad up-convertor to its CommLinkT family of digital radio ICs for fixed basestation applications.
The ISL51002 has three speed grades up to 165Msample/s to deliver resolution up to 1080p/UXGA at 60Hz, the latest available standard.
Its built-in black-level compensation prevents variations in colour or hue even variations caused by temperature change and its unparalleled DNL (differential nonlinearity), typically +0.86LSB at 165MHz, eliminates visible contour errors when digitising gradually changing images.
The remarkable channel linearity is only the beginning of the story though, as the ISL51002 comes with a host of features not available in competing devices.

Intersil has worked with Sony to develop Point Co-ordination Function (PCF) technology based on Intersil's latest Prism 2.5 wireless LAN chipset solution.
Wireless LAN technology for the workplace
Intersil is introducing a new brand of wireless products called Prism/work specifically designed to meet the growing need for wireless LANs in the workplace.
The ISL51002's digital PLL has high noise immunity and 250ns (typical), and 500ns (maximum), low jitter performance that eliminates the need for an analogue loop filter.
This highly innovative PLL is the easiest to use in the industry, with only one parameter needing to be programmed for optimal video performance.
The device also has an integrated sync measurement circuit that eliminates the development time of implementing this function in software.
This circuit analyses the incoming sync signals for type, polarity, period and pulsewidth.
These data, which are necessary for correct display, are read from internal registers through an I2C interface.
Additionally, the ISL52002 has an integrated automatic sampling phase adjust that evaluates 64 different sampling phases each second and selects the best phase to deliver the sharpest picture possible.
It also has a robust Macrovision-compliant sync separator that prevents visual disturbances when Macrovision-protected signals are displayed or head-switching noise from analogue VCRs is encountered.
The ISL51002's 4:1 mux input provides superior design flexibility.
Also simplifying design is an integrated RGB to YUV colour space convertor which allows the user to process an RGB signal in the YUV space.
The ISL51002 has unparalleled DNL (typical +0.86LSB at 165MHz), eliminating visible contour errors when digitising gradually changing images.
Target applications for the ISL51002 include flat panel TVs, front/rear projection TVs, PC LCD monitors and projectors, high-quality scan convertors and video/graphics processing.
The ISL51002 is available now in a 128-lead MQFP package.
