DALLAS -- Texas Instruments Incorporated (TI) (NYSE:TXN) today added a new category to its high-performance analog and mixed signal portfolio with the purchase of Graychip, the technology leader in re-configurable digital down converters (DDC) and digital up converters (DUC) for high-speed communications. Graychip's programmable digital converters provide the highest speed and flexibility as well as the industry's lowest power consumption. Digital converters provide the link between the digital signal processor (DSP) and data converters inside digital communications equipment. By shaping and filtering signals, they reduce noise and interference, thereby increasing the efficiency and bandwidth of the system. "This adds another link in the total signal processing chain that TI offers to customers. Graychip's in-depth systems knowledge in the high-speed signal processing domain, coupled with their strong portfolio of digital converters, provides complementary capabilities to TI's data converters and DSPs," said Gregg Lowe, TI vice president, High-Performance Analog Communications Products.
