VDSL2 line driver in 4mm x 5mm QFN package is a first says Intersil
Intersil has introduced the ISL1539, the latest addition to its family of line drivers featuring low power, very small footprint and extremely good linearity. The ISL1539 is the first monolithic, dual port, DSL line driver for 100 Mbps VDSL2 Central Office (CO) applications. The ISL1539 uses proprietary circuitry to achieve low distortion, high capacitance drive and less than 910mW/port total power consumption while delivering 20.5dBm output pow...
True Femto-Second Performance Clock Generator for Networking Designs
Texas Instruments has introduced a low-phase noise clock generator that provides best-in-class jitter performance at 380 femtoseconds (fs) (rms at 10 kHz to 20 MHz). The device incorporates crystal oscillator (XO) circuitry with a fully-integrated frequency synthesizer supporting a wide output frequency range from 10.9 MHz up to 766.7 MHz and from 875.2 MHz up to 1175 MHz, easing design for customers designing Ethernet, fibre channel, PCI Express...
Low-Power Gigabit Ethernet serializer/deserializer
Texas Instruments has today introduced the industry's smallest low-power, single-channel Gigabit Ethernet (GbE) serializer/deserializer (SerDes) device, enabling higher densities in data communications and telecommunications equipment. The new interface device combines a small 6-mm x 6-mm package with low power consumption at 200 mW to reduce board size and complexity and save power in Ethernet passive optical networks (EPON), GbE switches/router...
Two-chip IF receiver solution from Analog Devices
Analog Devices has introduced a two-chip IF (intermediate frequency) receiver solution that dramatically improves the data bandwidth and capacity of next-generation, multi-carrier wireless base stations compatible with emerging 3G cellular transmission standards. Analog Devices’ dual-channel AD8376 VGA (variable gain amplifier) and AD6655 IF diversity receiver solution replaces 48 discrete components, enabling 3G micro- and pico-cell base s...
Low power, asynchronous PCI-to-PCI bridge
Tundra Semiconductor is now in full production of its low power, asynchronous PCI-to-PCI bridge. The Tundra Tsi350 offers communications and network equipment customers a competitive high quality bridge solution with low power consumption.
Multipoint-LVDS Single-Channel Receivers from TI
Texas Instruments has introduced what is said to be the industry's first dedicated multipoint-LVDS receivers. To date, customers converting M-LVDS to LVTLL for multi-drop clock distribution have used transceivers with unnecessary integrated driver circuitry. The new single-channel receivers save space, power consumption and cost in end equipment such as cellular base stations, central office switches, network switches, routers and AdvancedTCA sys...
Zetex announces technology breakthrough in LNB design
