NXP Semiconductors has announced that Comba Telecom Systems Holdings Limited (Hong Kong stock code: 2342) has selected NXP high speed converters (HSC) for use in its digital repeater products. Comba, a leading wireless enhancement solutions provider, will be using NXP digital-to-analog converters (DAC) in the transmitter of its digital cellular repeaters.

Digital repeaters are used in large indoor and outdoor spaces such as high-rise buildings, shopping malls, tunnels and stadiums to strengthen cellular phone signals, enabling mobile network operators to extend voice and data services to areas that would otherwise not have coverage. Comba's digital RF repeaters are particularly well suited for dense urban environments, and have proven popular with wireless network owners and operators as a cost-effective solution for optimizing network performance. Using advanced digital signal processing technologies, Comba's digital repeaters support features such as Uplink Noise Control (UNC) and Antenna Feedback Stabilization (AFS), which significantly reduce interference as well as deployment time.

"We appreciate the support NXP has provided to Comba's development team, and look forward to continuing the productive relationship we've established with the NXP high speed converter business," said Mr. David Luo, director of R&D, wireless department, Comba Telecom Systems.

"NXP is very happy to be working with Comba, providing our state-of-the art high speed data converters, as well as design-in services," said Maury Wood, general manager, high speed converters product line, NXP Semiconductors. "Comba is a world leader in wireless enhancement, and we are proud to offer converters that meet the group's demanding technical requirements."

NXP's portfolio of high speed converters includes the industry's first implementation of the JESD204A high-speed serial interface, available on both ADCs and DACs. NXP CGV™ technology is an enhanced implementation of JEDEC JESD204A, which radically simplifies PCB layout and channel synchronization, enables dramatic improvements in system performance over conventional parallel interfaces, and significantly reduces bill of materials (BOM) costs.
