NXP Semiconductors has announced the availability of a new family of common mode filters with integrated ESD protection for high-speed MIPI D-PHY and HDMI interfaces.
The new PCMF series offers a typical common mode rejection of more than 12 dB in the band between 300 MHz and 8 GHz. The PCMF2DFN1 (for two differential line pairs) and the PCMF3DFN1 (for three line pairs) 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.
With their simplified “out-of-the-box” design, these products help to accelerate time-to-market. In addition, 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.
Additional features include good system-level ESD protection due to deep-snapback and low dynamic resistance, support for all MIPI D-PHY data rates up to 1.5 Gbit/s and compliance to the HDMI eye diagram requirement at 3.4 Gbit/s.
