ANR Headset lets user control ambient sound level entering ear.

February 26, 2015

Hurricane III, with SureFire EarLock® Retention Rings and Noise-Reducing Filters, provides up to 40 dB of protection against loud noises while preserving situational awareness. In open position, Noise-Reducing Filters allow ambient sounds and conversations to be heard clearly. In very high noise environments, closed position reduces ambient background noise by 21 dB. Low-profile design, which can be worn while wearing helmet or mask, also includes noise-canceling microphone. Read More

Common Mode Filters combine EMI filtering, ESD protection.

May 31, 2011

Supporting data speeds to 3.4 Gbps, silicon-based EMI2121 (single pair), EMI4182, (dual pair) and EMI4183 (triple pair) offer common mode rejection of 15 dB typ at 500 MHz and insertion loss of 1.0 dB typ at 500 MHz. Integrated ESD protection, which meets peak discharge of 15 kV per IEC61000-4-2, and differential mode bandwidth cutoff frequency optimize signal integrity. CMFs protect high-speed differential ports using MIPI DSI/CSI2, USB 2.0, and HDMI interface standards. Read More

Clock IC filters jitter from networking systems.

July 29, 2010

Designed to remove unwanted noise on any clock frequency from 1-710 MHz, pin-controlled Si5317 produces 2 ultra-low jitter output clocks at same frequency as input. Unit delivers jitter performance of 0.29 ps rms, optimizing BER and SNR in jitter-sensitive applications. Integrating single supply voltage regulator, IC eliminates need for multiple supply rails and discrete ferrite beads. On-chip DSPLL technology eliminates need for charge pump and/or loop filter.
