T-DMB single-chip highly integrated
solutions

T-DMB (Terrestrial Digital Multimedia Broadcasting) is one of the mobile TV standards that originated from the incumbent DAB standard (Eureka147). Currently, T-DMB is under deployment or trial service in Korea, China, and Europe. Korea launched T-DMB service in 2005. The main applications include wireless handsets, notebook PCs, and car-navigation.

GDM7004

GDM7001GCT's GDM7004, a single-chip optimized for T-DMB service, uniquely integrates the following three functions: RF, channel decoder, and memory. Through this high level of integration, GDM7004 offers an extremely small form factor and low power consumption.

Since T-DMB service is mainly deployed in two operating bands - Band III and L-Band - GDM7004 is able to offer a flexible RF receiver path for both bands. In addition, the external memory is not required for T-DMB functionality.

GDM7004 Features:

  • Single-chip solution
  • Single clock at 32.768MHz enables both RF and CDM
  • Carrier frequency for Band III and L-Band
  • SPI and 16bit host I/F
  • Adapts GCT's proprietary algorithm for mobile broadcast reception

GDM7004 Benefits:

  • Low power consumption
  • Industry's smallest form factor
  • Best reception performance
  • Lower material cost
  • Combats hostile wireless environment
