H.264 codecs provide compression performance that delivers more than 50% greater efficiency than MPEG- 2. The CX2418X family is the first set of products to result from Con- exant’s acquisition of Amphion Semiconductor in June 2004. The CX2418X family is based on the ARM926EJ-S core. Samples now; production in Q2’05; $20 @ 10Ku. Jeff Crosby, VP of Broadband Me- dia Processing Products. www. conexant.com
On the heels of the official ratifica- tion of the ZigBee Specification, Ember has introduced a new version of its wireless networking platform that is designed to be fully ZigBee compliant, once official testing be- gins in the coming weeks. Ember’s ZigBee software together with its EM2420 chip is claimed to be the first single source platform to feature an 802.15.4-compliant radio and a ZigBee protocol stack in a develop- ment environment. The platform sup- ports pre-defined stack profiles like Home Controls for home automation applications, as well as a customer configurable stack profile. Ember claims that its solutioh is implement- ed in 80% of the ZigBee design wins today. Venkat Bahl, VP of market- ing. www.ember.com
Freescale’s ZigBee-enabled plat- form scored high marks in L.S. Re- search’s evaluation tests by achieving over 378 meters (1,240 feet) of range without the aid of external power amplifiers or low noise amplifiers. This far exceeds the ZigBee Alli- ance’s recently ratified 1.0 specifi- cation with expected ranges between 10-70 meters at low power. The MC13193 RF transceiver is $3.26 @ 10Ku.

Ikanos has entered the market for VDSL2 equipment with two new programmable chipsets, the Smart- Leap 9400 for Central Office (CO) and Remote Terminal (RT) equip- ment and the CleverConnect 600 for Customer Premise Equipment (CPE). The proposed VDSL2 stan- dard by the ITU-T brings conver- gence between ADSL, ADSL2+ and VDSL.
The SmartLeap 9400 VDSL2 Chipset for CO/RT applications has three main elements: 8-port Burst- Mode Engine (BME) that integrates an embedded 150 MIPS processor, ATM and IP (PTM, EFM 64/65) in- terfaces and DSP function; 4-port AFE with ADC/DAC; and 1-port In- tegrated Front End (IFE) that inte- grates line drivers, capacitors, filters and other discrete components.
The CleverConnect 600 VDSL2 Chipset for CPE consists of two chips: 1-port BME that integrates ATM, IP, DSP functions along with ADC/DAC and 1-port IFE. The de- vices support dual-mode program- mability that enables carriers to select ATM or IP on a per-port basis. Broadband equipment can be pro- grammed to supportVDSL2, VDSL, and VDSL long range (VLR) in both ATM or IP modes, as well as ADSL and ADSL2+ in ATM mode. Sam- ples in Q1’05.

Inphi has introduced a Registered Buffer with Parity Checking family operating at 400, 533 and 667 Mbps using 2nd generation DDR2 technol- ogy. The registers are part of the In- phi ExacTik family of precision timing devices. The devices support all existing standards of DDR2-400 and DDR2-533 as well as future stan- dards for server memory operating
at DDR2-667. Desi Rhoden, EVP. www.inphi-corp.com
Microchip has introduced the PIC- DEM Z 2.4 GHz Demonstration Kit that supports the ZigBee standard protocol for wirelessly networked control and monitoring applications. The PICDEM Z platform provides a free ZigBee protocol software stack and incorporates Chipcon’s CC2420 2.4 GHz RF transceiver. Microchip offers over 30 PIC18 8-bit microcon- trollers that support the ZigBee soft- ware stack and incorporate nanoWatt technology power-managed modes and self-programmable Flash pro- gram memory.

NewLogic is supporting IEEE 802.11h with an improved radar de- tection algorithm within its 802.11 WiLD WLAN IP blocks comprised of triple mode a/b/g MAC, Modems and Radio. The 802.11h extensions will be required in all 802.11a com- pliantAccess Points andAd-Hoc sys- tems by the beginning of 2005 in Europe and will also be applicable to North America in order to avoid interference with military radar ap- plications.
The proper detection of radar pulses necessary for support of 802.11h is a thorny problem. The biggest issue is not to detect radar but to avoid false detections, which must be kept to a minimum due to the fact that a chan- nel in which radar is detected has to be blocked for WLAN transmission for at least 30 minutes. If the false alarm rate is too high, too many chan- nels are blocked and the WLAN net- work can rapidly become saturated. European regulations are available today but are still evolving; discus-
