California Micro Devices Establishes New Price/Performance Standard With 0.4mm Pitch Chip Scale Centurion(TM) EMI Filters

Posted on: Tuesday, 30 August 2005, 09:00 CDT

MILPITAS, Calif., Aug. 30 /PRNewswire-FirstCall/ -- California Micro Devices today introduced a new family of Centurion(TM)-based ASIP(TM) (Application Specific Integrated Passive(TM)) EMI (electromagnetic interference) filter arrays, offering superior EMI filtering performance combined with robust ESD (electrostatic discharge) protection in reduced form factor, 0.4 mm pitch Chip Scale Packages (CSP). The introduction of these new Centurion(TM) ASIP(TM) devices redefines existing price/performance standards for EMI filters used to filter and protect LCD display, camera module and dataport interfaces in mobile handset applications. They deliver the highest levels of EMI filter and ESD performance in form factors that are more than 30% smaller than existing 0.5mm pitch CSP products. Additionally, the new fine pitch CSP ASIP(TM) devices are priced to offer significant savings when compared to 0.5mm CSP ASIP(TM) devices and equivalent solutions housed in TDFN packages.

With the penetration of advanced multimedia capabilities increasing drastically in wireless handsets, finding space to allow the integration of additional modules is becoming more and more challenging for platform designers. In parallel, data interface rates for the handset's LCD display and camera module interfaces are increasing significantly as the pixel resolution of these components increases. Handset designs featuring these high speed parallel data interfaces face more challenging EMI filtering and ESD protection issues. In order to satisfy these requirements, CMD has raised the bar in terms of form factor and performance by delivering a new family of 0.4mm pitch CSP EMI filter ASIP(TM) devices with ESD protection. The new CM1440, CM1441 and CM1442, developed in CMD's Centurion(TM) process, offer a high level of EMI filtering performance for various capacitance budgets and channel configurations in order to address a broad range of requirements and applications in the smallest form factor available on the market.

Key Features

The CM1440, CM1441 and CM1442 EMI filters with ESD protection are based on a 2-pole C-R-C filter architecture. The electrical parameters of these products are summarized below:

Configuration # of Attenuation Attenuation Cutoff 2-pole C-R-C Channels @ 900MHz 800MHz- Frequency 2.7GHz CM1440-06 30pF-100Ohms-30pF 6 EMI/ESD -42dB -35dB 60MHz CM1441-07 30pF-100Ohms-30pF 4 EMI/ESD -42dB -35dB 60MHz +4 ESD CM1442-06 15pF-100Ohms-15pF 6 EMI/ESD -33dB -32dB 120MHz CM1442-08 15pF-100Ohms-15pF 8 EMI/ESD -33dB -32dB 120MHz

With fast cutoff frequencies, steep roll-offs and deep attenuation, these new products are ideal for filtering display and camera module interfaces operating at data rates up to 25MHz. In addition to filtering, these products also feature ESD protection up to +/-15kV contact discharge per IEC61000-4-2 Level 4 specification.

Ultra Compact Footprint

This new product family demonstrates CMD's commitment to help wireless handset designers solve key implementation issues such as minimizing board space and optimizing the overall system robustness against EMI radiation and ESD strikes. The CM1440, CM1441 and CM1442 EMI filters are offered in the industry's smallest form factor, and contribute to a space savings of up to 42% when compared to existing TDFN solutions, and greater than 30% when compared to 0.5mm CSP solutions. CMD's new fine pitch CSP ASIP(TM) devices feature a combination of EMI filtering performance and ESD protection that cannot be met by discrete components, ceramic-based products or even similar ASIP(TM) architectures housed in TDFN packages.

Pricing and Availability

The CM1440, CM1441 and CM1442 are available for sampling immediately. Production for both families is scheduled for Q3 2005. Pricing starts at $0.36 each in 1,000 unit quantities for the six channel version and $0.42 each in 1,000 unit quantities for the eight channel version. CMD can apply its proprietary OptiGuard(TM) technology to all of its CSP products to increase robustness and durability during placement on PCBs in the manufacturing process. These products are available in RoHS compliant lead free CSP.
