Pulse's ChipChoke series for USB2.0 standard applications are said to eliminate common mode noise in high-speed networks.
Transformer boosts reliability and performance
Pulse, a Technitrol Company, has introduced the C2139NL RF balun transformer for radio frequency (RF) applications ranging from 5 to 1000 megahertz (MHz) bandwidth.
At 17 x 13mm, the B8849NL is one-third the sise of standard B8049 Smart modules and handles frequencies of 30MHz, compared with 2.2MHz for the Smart modules.
Pulse's SmartER series defines the new package and footprint standard for xDSL modules providing a reliable, lower-cost solution.
"New demands by consumers requiring higher datarates have created a challenge for the telecom industry to come up with reliable VDSL2 components", said Philippe Duchatel, Senior Product Manager for Pulse's Telecom Division.

"Pulse defined the Smart footprint that is now being used as the industry standard".
"With our new SmartER module we have again set the standard for this next-generation technology".
The SmartER modules are made with passive discrete components and a patented core material.
They are used in telco central offices (CO) to achieve excellent voice quality by separating voice and data signals and filtering interference out of the data signals in xDSL applications, including VDSL2.
The latest and most advanced DSL broadband wireline standard, VDSL2 is designed to support the wide deployment of triple play (voice, video, data) services such as high-definition television (HDTV), and interactive gaming.
SmartER modules can be used in two network architectures.
One delivers signals to the home in the traditional manner, from CO splitter boards via copper wire.
The second delivers the signals from splitter boards in nearby street cabinets, such as those used in fibre to the cabinet (FTTC) applications, in which the last mile of the signal travels over copper using VDSL2 technology.
SmartER modules address the challenge of carrying more channels and handling higher frequencies while fitting into street cabinets with limited space.
SmartER modules are case-less through-hole designs with four pins in a very compact 12 x 11mm footprint.
This small footprint enables more components, and therefore more lines, to fit on a splitter board at the CO, reducing the cost of the overall splitter solution.
Pulse's new series of filters can also be used on a customer premises equipment (CPE) modem board for single-line lowpass filter solutions.
With the development of triple play services, the trend is to move from simple modem to multi-function integrated gateways with onboard filtering rather than an external filter solution.
The compact design of the SmartER series addresses the space issue on these gateways.
The SmartER B8849NL design is dedicated to the ETSI complex impedance option A standard.
The series will expand rapidly to cover all ANSI, ETSI, and ITU standards for ADSL, ADSL2+ and VDSL2 applications.
Modules in the SmartER series are RoHS-6 compliant.
The splitter/filter modules are pin-to-pin compatible so the same board layout can accommodate different standards for different countries just by changing the component model.
The B8849NL is a fully tested filter and a ready-to-use electrical module.
System integrators need only supply the mechanical functions to the splitter board.
Pulse's B8849NL filter modules are available in trays.
