NXP Semiconductors N.V. (NASDAQ: NXPI) today announced the availability of a new family of Common Mode Filters (CMF) with integrated ESD protection for high-speed MIPI D-PHY and HDMI interfaces. Offering industry-leading bandwidth for Common Mode suppression as well as strong system-level ESD protection, the PCMF2DFN1 (for two differential line pairs) and the PCMF3DFN1 (for three line pairs) outperform all other silicon or ceramic-based solutions currently on the market. The PCMF family comes in small and thin DFN packages with a maximum height of 0.5 mm and an industry standard footprint, supporting the compact and slim designs of today’s smartphones, tablets and other portable devices.

Wide-band suppression of Common Mode noise
The PCMF series offers a typical Common Mode rejection of more than 12 dB in the band between 300 MHz and 8 GHz. The PCMF2DFN1 and PCMF3DFN1 are the only available devices offering a typical Common Mode rejection of >18 dB for Wi-Fi 4.9-5.8 GHz frequencies, in addition to a typical Common Mode rejection of > 20 dB around the GSM 900 spectrum. The products help to accelerate time-to-market due to their simplified ‘out-of-the-box’ design. The wide bandwidth supported by the PCMF series means that manufacturers, no longer have to spend time trying different narrow-band filters in order to find the right solution. PCMF-series offers industry leading bandwidth for common mode suppression covering all typical data rates and their higher harmonics.

Superior differential signal integrity
With a differential pass-band covering more than 2 GHz, the PCMF series supports all MIPI D-PHY data rates up to 1.5 Gbit/s, and even passes the HDMI eye diagram requirement at 3.4 Gbit/s, as verified by the independent Authorized Testing Center in Caen.

Deep snapback, low dynamic resistance for high system-level ESD protection
ESD pulses can couple to data lines – even in closed cases through gaps, such as the camera fitting in mobile phones or tablets. To address this, the PCMF series features ESD protection with NXP’s industry-proven deep-snapback technology. Protection devices with deep-snapback technology show a negative dynamic resistance when triggered by an ESD event. In addition, the value for the dynamic resistance after the snapback is the lowest available for common mode filters with ESD-protection. This combination ensures the best possible protection of sensitive System on Chips.

Key Features of PCMF2DFN1 and PCMF3DFN1
•Industry-leading bandwidth of Common Mode rejection
•Superior differential signal integrity, passes the HDMI eye diagram requirement at 3.4 Gbit/s
•Industry-leading system-level ESD protection due to deep-snapback and low dynamic resistance
•Package with 0.5 mm maximum thickness, using an industry-standard footprint
