ADMTV800:  UHF/S-Band Tuner IC for CMMB

Product Description

The ADMTV800 is a highly integrated CMOS zero-IF conversion tuner IC for China Multimedia Mobile Broadcasting (CMMB). The part includes dual RF input bands, UHF and Sband. The building blocks of the ADMTV800 include LNA, RFPGA, I/Q downconversion mixer, bandwidth adjustable lowpass filter, baseband PGA and fractional-N frequency synthesizer with fully integrated VCO and PLL loop filter. The on-chip low phase noise VCO, along with the high resolution fractional-N frequency synthesizer makes in-band phase noise low enough for mobile TV applications.

By using very small package size (LFCSP, WLCSP), the ADMTV800 is the best solution for CMMB application especially for mobile phones, notebook PCs, PDAs, etc. where low power consumption is critical. The part has an I2C serial bus interface.

Applications

  • CMMB mobile and portable TV receivers
