STMicroelectronics' IPAD(TM) Technology Shrinks and Simplifies Protection for High-Bandwidth Connections

The ECMF02 and ECMF04 are the industry's first silicon-based ICs to combine the common-mode filtering and ESD protection needed by high-speed data lines. Common-mode filtering prevents data errors caused by electromagnetic interference (EMI), and is usually implemented using a separate ceramic-type component. ST's new devices enable a cost-effective single-chip solution saving printed-circuit-board (PCB) space and simplifying design and assembly.

ST currently supplies more than 30% of all IPAD components worldwide and has patented a new filter topology to realize the Common-Mode Filter (CMF) in silicon. This represents a technical breakthrough that will save up to 50% of the PCB space typically needed to implement the CMF and ESD protection separately. The devices are also only 0.55mm high, which will help designers create ultra-slimline products.

Major features:

    --  ECMF02 - single-channel device
    --  ECMF04 - two data-channel device
    --  6GHz differential bandwidth, complies with HDMI, MIPI D-PHY and USB2.0
    --  High common-mode attenuation:
        --  -34dB at 900MHz
        --  -20dB between 800MHz and 2.2GHz
    --  High ESD protection with low remaining voltage (Vpeak < 50V)
    --  Flow-through pin-out enabling efficient, simplified PCB layout

The devices are available immediately for quantities of 5000 pieces, priced at $0.18 for the ECMF02-2AMX6 (6-lead uQFN package) and $0.36 for the ECMF04-4AMX12 (12-lead uQFN). Alternative pricing options are available for larger quantities.
