GCT Semiconductor delivers world's most integrated monolithic single-chip solution for terrestrial-digital multimedia broadcasting (T-DMB) Mobile TV applications

With the smallest form factor and lowest power consumption on the market today,
GCT's single-chip represents the optimal solution for handheld, mobile T-DMB applications.

SAN JOSE, CA, October 18, 2006 -- "GCT Semiconductor, a leading provider of highly integrated semiconductor solutions for wireless communications, today announced a cutting-edge monolithic single chip, GDM7004, which fully integrates the RF tuner and the channel decoder for T-DMB applications. GDM7004 includes all the major components required to implement a T-DMB receiver, supporting Band 3 and L-Band. This single-chip also comprises an analog baseband, an A/D converter and a digital demodulator, as well as a channel decoder and host interfaces. When connected with an A/V processor, GDM7004 represents the world's most integrated total solution for T-DMB available today.

"GCT is committed to delivering a range of products for the growing mobile TV market,"commented Dr. Kyeongho Lee, President and CEO of GCT Semiconductor. "With our expertise in developing highly integrated semiconductor solutions, we've well positioned to launch this monolithic T-DMB chip for mobile and handheld devices as an extension of GCT' success with its state-of-the-art S-DMB solutions. The new GDM7004 represents the first fully integrated single chip for the T-DMB market with minimum BOM and extremely high performance."

T-DMB service is rapidly gaining popularity in Korea, with over 1.6 million receivers sold as of August 2006. T-DMB service is currently commercially on-air in Korea, with field trials on-going in China and several European countries.

GDM7004 utilizes state-of-the-art direct conversion (zero IF) RF, removing the need for costly and space-consuming IF, SAW filtering. Housed in 121pin LFBGA (8mmx8mmx0.9mm), this solution offers full capacity of ensemble de-interleaving using embedded SRAM, as well as low power consumption under 100mW. GCT established proven reference designs with major multimedia processors for T-DMB handsets and other applications. Evaluation kits and samples are available.
