Filter modules improve voice quality
Integrated lowpass splitter/filter modules improve voice quality by separating voice and data signals and filtering interference out of the data signals in xDSL applications.
Focus EDL has a series of xDSL integrated lowpass splitter/filter modules designed to achieve excellent voice quality by separating voice and data signals and filtering interference out of the data signals in xDSL applications Produced by Pulse, the filters are complete, ready-to-use electrical modules - system integrators need only supply the mechanical functions to the splitter board

Speedy access for 16Mbit Flash
The Eon Silicon Solutions EN29LV160 is a 16Mbit erasable, read/write nonvolatile Flash memory.
And, because they integrate up to 15 inductors, capacitors and resistors into a fully tested, compact, through-hole package, these filter/splitter modules save designers considerable time and expense of building filters from scratch.
The splitter/filter modules meet the full range of ANSI, ETSI, and ITU standards for ADSL and ADSL2+, thus covering all xDSL applications worldwide.
Some VDSL2 compatible modules are already available.
Pulse's SMART series of splitter/filter modules are pin-to-pin compatible so that the same board layout can accommodate different standards for different countries by just changing the component.
The SMART modules support plain old telephone service (POTS), integrated services digital network (ISDN), and voice over Internet protocol (VoIP) installations.
They can be used in central office (CO) applications as single-line lowpass filter solutions mounted on the digital subscriber line access multiplexer (DSLAM), multiservice access node (MSAN) splitter board, or main distribution frame (MDF).
They can also be used in customer premises equipment (CPE) applications enabling the lowpass filter function to be embedded inside the modem or home gateway.
