Display controller suits advanced
handsets
California Micro Devices' architecture will permit handsets that use CPUs and application processors with on-chip MDDI compatible hosts to interface with LCD modules with MDDI or MIPI-based clients.
California Micro Devices has developed a display controller architecture that meets both the Mobile Display Digital Interface (MDDI) and Mobile Industry Processor Interface (MIPI) standards for high-speed serial display interfaces for use in advanced mobile handsets The architecture will permit advanced handsets that use CPUs and application processors with on-chip MDDI compatible hosts to interface with liquid crystal display (LCD) modules that feature either MDDI or MIPI based clients

Small flash LED driver for mobile handsets
California Micro Devices has unveiled a new family of PhotonIC white LED drivers capable of supporting a wide range of high current flash LEDs in today's most advanced handsets.
The existence of the two standards for high-speed serial display interfaces has compelled handset makers to procure different LCD modules which are based on the serial interface standard supported by their selection of CPU architecture.
With the development of products based on the new MDDI-to-MIPI bridge architecture, handset makers using a CPU with an MDDI-based host will have the flexibility to procure either a display module with an MDDI based client or a MIPI based client.
This will allow handset makers that produce models using both MDDI and MIPI-based CPUs to satisfy all of their display requirements with modules based on the MIPI standard, resulting in higher volumes and lower module prices.

Range cuts the cost of inductor-capacitor filters
LC filters allow mobile handset designers to address many higher bandwidth data interfaces that cannot be served by lower cost resistor-capacitor based devices.
In addition to providing multistandard display module support for MDDI-based CPU handset designs, products based on the new MDDI-to-MIPI bridge architecture will also be able to interface to existing GSM and WCDMA baseband and application processors via an industry standard CPU interface.
This will provide handset makers seeking an early introduction of MIPI-based handset designs with the flexibility of using widely available GSM and WCDMA CPUs without an integrated MIPI host.
Handset makers can reduce product launch risks associated with dependence upon new product development schedules while taking full advantage of the benefits of a high-speed serial display interface, which include a reduced number of interface signals, lower power consumption and reduced electromagnetic interference (EMI).
"Handset makers that produce systems based on both the GSM and CDMA standards and associated 3G standards, will have the opportunity to achieve cost savings as a result of concentrating their purchasing power on procuring LCD modules based on a single standard while also enjoying the cost, space, power and EMI reduction advantages inherent in the use of the serial interface", said Kyle Baker, CMD's Vice President of Marketing.
