Board makes the most of Marvell

Dialog Semiconductor’s new evaluation board for its DA9034 integrated chip enables designers to quickly configure designs based on Marvell PXA3xx application processors. The board, which provides an audio- and powermanagement solution for Marvell PXA3xx-based products, is driven using a standard Windows-based graphical user interface (GUI) via a personal computer’s USB interface.

With the DA9034-EVB, developers can evaluate the technical performance of the DA9034 highly integrated audio- and power-management IC. The DA9034-EVB can also be used in conjunction with a PXA3xx processor system to develop power-management and audio-control routines, as well as verify complete designs.

The board provides a reference pc-board layout and uses components typically found in cellular-handset, portablemedia- player, and PDA designs that are optimised for low build height of less than 1.2mm, and minimum pc-board area.

Dialog’s DA9034 IC integrates more than 50 mixed signal functions on a single chip, providing regulated supplies for the PXA3xx processor, memory, and peripheral devices as well as supporting lithium-ion-battery charging, touch-screen interface, and LED driving together with voice and HiFi audio codecs.
