3rd Generation Groundbreaking EMI Filter Technology Offers Excellent Signal Integrity and Superior EMI Filtering MILPITAS, Calif., March 3 /PRNewswire-FirstCall/ -- California Micro Devices (NASDAQ:CAMD) today announced the CM1693 family of advanced EMI (electromagnetic interference) filters based upon the company's Praetorian III LC based filtering technology. The CM1693 is the first device to meet exacting EMI filter and ESD (electrostatic discharge) protection requirements while offering the low line capacitance necessary for the increasingly higher speed data interfaces to the high resolution cameras and displays used in today's most popular feature and smart phone models. The CM1693 also provides superior attenuation in the 700 MHz band, making it the optimal solution for handset designs based upon 4G LTE based processors.

Praetorian III products offer higher performance than Praetorian I products, at lower cost equivalent to the recently introduced Praetorian II family of products. Praetorian III filter designs employ higher levels of inductance and lower levels of capacitance to deliver industry leading EMI suppression, excellent signal integrity and robust ESD production in a space efficient, single chip solution. Application Requirements for Feature and Smart Phones Smart phone adoption is outpacing the growth rate of the overall wireless handset market. The typical smart phone feature set includes high resolution user interfaces such as cameras and displays, and high capacity removable memory modules for data-rich multimedia applications. Inductor based LC solutions like the CM1693 are ideal for EMI filtering and protecting high speed parallel data interfaces in applications where digital signal integrity is critical, such as high megapixel cameras, high density removable memory modules, and high resolution displays. Main Features Key performance attributes of the CM1693's scalable pi-filter topology include: -- Typical roll off frequencies of 300 MHz -- Broad stop band starting in 700 MHz band up to 6 GHz -- High levels of attenuation and robust ESD protection up to plus or minus 18kV contact discharge, consistent with the IEC 61000-4-2 level 2 standard -- Superior signal integrity with rise and fall times less than 4ns -- Minimal insertion loss (
