Filters smooth out VDSL modems
A new family of filter modules can replace as many as 20 individual discrete components when used with VDSL chipsets.
Pulse has a new family of filter modules, part numbers BX4037, BX4038, BX4039 and BX4040, for use with very-high-bitrate digital subscriber line (VDSL) chipsets 20 individual discrete components can now be replaced with just one Pulse VDSL module, minimising component footprint, freeing up board space and reducing cost

New choke eliminates common mode noise
Pulse's ChipChoke series for USB2.0 standard applications are said to eliminate common mode noise in high-speed networks.
The multifunction modules include a highpass filter, a hybrid transformer, transmit (TX) and receive (RX) separation filter and a common-mode choke.
The modules meet IEC950 supplementary insulation requirements with the most compact footprint in the industry.
Each module's surface mount (SMT) package is compatible with all contemporary pick-and-place manufacturing processes.
Line return loss between 4.1 and 7.9MHz is 12dB.
The isolation voltage is rated at 1500V RMS.
Line impedance is rated at 120ohm, TX impedance at 40ohm and RX impedance at 270ohm.
An extended operating temperature range of -40 to +85C ensures product stability with minimum drift under a wide range of conditions.
Model numbers BX4037 and BX4038 with four ports are available in quantities of 25 units per tray.
Model numbers BX4039 and BX4040, single ports, are available in quantities of 30 units per tube or 650 units per tape and reel.
Lead-time is four to six weeks.
