CGVxpress High Speed Serial Interface from NXP targets wireless applications
CGVxpress will be used in future NXP ADC and DAC product families, and will be demonstrated for the first time at the IEEE International Microwave Symposium (MTT-S) from 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.
CGVxpress dramatically reduces the number of interconnect signals between the data converters and logic devices. It also solves a major base station system design challenge by synchronously bonding multiple data lanes with sample level accuracy. Further, CGVxpress facilitates significantly reduced PCB design and manufacturing complexity, impacting both NRE costs and marginal production costs; systems can often be implemented using fewer PCB layers as compared to traditional parallel interfaces.
Maury Wood, product line general manager, high speed converters, NXP Semiconductors comments, “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.
