I had the pleasure to talk with Maury Wood, general manager, High Speed Converters for NXP. Here we discussed the innovations that NXP is bringing to the fast growing and demanding communications sector. NXP is a leader in high performance mixed-signal IC products and the recognized leader in SERDES-based serial interfaces for high speed converters. NXP offers a broad selection of high-speed data converters, with digital interfaces including JESD204A-compliant CGV, CMOS LVCMOS and LVDS DDR interfaces. These high speed converters are suitable for wireless infrastructure, industrial, scientific, medical, aerospace and defence applications.
NXP Semiconductors N.V. (NASDAQ: NXPI) announced the DAC1627D - a 16-bit dual-channel LVDS DDR interface Digital-to-Analog Converter (DAC) which supports output update rates of up to 1.25 Gsps. In terms of dynamic performance specifications, this new high-speed DAC offers best-in-class single tone SFDR performance and two-tone intermodulation distortion over a broad output bandwidth of 200 MHz. First public demonstration of the DAC1627D will be made in the NXP booth (no. 420) at IMS2011, the IEEE MTT-S International Microwave Symposium held June 7-9, 2011 in Baltimore, Maryland. Developed primarily for wireless infrastructure applications, the DAC1627D1G25 is fully compliant to the Multi-Carrier GSM spectral mask and the LTE and LTE-Advanced transmit specification, with comfortable margins. As a result, the DAC1627D is ideal for multi-standard radio base stations, allowing design engineers to employ a single DAC transmit architecture, which minimizes the system bill-of-material costs. "The technology advances in cellular infrastructure demand ever higher performance in RF data converters. The introduction of NXP's DAC1627D, its high performance and high-speed digital to analog converter device, provides a compelling solution in this quickly evolving segment," said Flint Pulskamp, wireless and wired communications semiconductor analyst at IDC.

"The achievement announced today, the highest performance RF DAC, is a culmination of decades of experience and innovation in high performance data converters," said Maury Wood, general manager, High Speed Converters product line, NXP Semiconductors. "When combined with CGVxpress™ and CGV™, NXP's implementation of the industry-leading JESD204A high speed serial interface, NXP has a roadmap that meets the most demanding digital radio transmitter signal fidelity requirements. NXP continues to work closely with our customers to bring new levels of radio frequency digital-to-analog performance to next-generation radio base stations, and other digital communications and signal synthesis applications." The DAC1627D incorporates elements of NXP's CGV technology feature set, including Multi-Device Synchronization (MDS), which solves tough system synchronization and latency challenges in many digital communications system applications, including MIMO and active antenna array LTE radio base stations. At IMS2011, NXP will also showcase the DAC1627D1G25 plus the BGX7100 IQ Modulator on a dedicated evaluation/demonstration printed circuit board which, in combination, deliver optimum RF performance. Product information on the DAC1627D is available at: www.nxp.com/pip/DAC1627D1G25HN.html
NXP has also announced CGVxpress™, an important extension to its high speed data converter technology portfolio and the next generation of the CGV™ high speed serial interface announced in 2009. The newly announced CGVxpress will be used in future NXP ADC and DAC product families. The first demonstration of CGVxpress will occur at booth #420 of the IEEE International Microwave Symposium (MTT-S) held June 7-9, 2011 in Baltimore, Maryland. NXP will showcase a 4.5 Gbps CGVxpress transmitter interworking with an industry standard FPGA over a 20 cm differential data lane. CGVxpress (Convertisseur Grande Vitesse or High Speed Converter) interface technology is ideal for: wireless infrastructure (WIFR), industrial, scientific, medical (ISM), and aerospace and defense (A&D) applications, where high bandwidth, sample accurate lane synchronization and deterministic latency are critically technical requirements. The CGVxpress feature set also includes support for Multi-Device Synchronization (MDS). MDS solves tough system synchronization and latency challenges in many digital communications system applications, including LTE and LTE-Advanced MIMO radio base stations. "NXP continues to strengthen its leadership position in high-speed serial interfaces with a major enhancement to CGV, and set the pace for data converter innovation," said Maury Wood, product line general manager, high speed converters, NXP Semiconductors. "CGVxpress delivers value that goes beyond traditional parallel interfaces, providing dramatic enhancements to ease-of-use, cost benefits and system architecture. The technology and performance enhancements enabled by CGVxpress will drive this serial interface into ubiquitous adoption by data acquisition system engineers worldwide." The CGV interface currently appears on several products in NXP's high speed ADC and DAC product line -- including the ADC1413D and DA1408D product families. Additional Benefits
