ADMTV102

The ADMTV102 is a highly integrated CMOS, single-chip, zero-IF conversion tuner IC for mobile TV standards, such as DVB-H, DVB-T, DTMB, and CMMB. The part includes an RF input band, UHF. The building blocks of the ADMTV102 include LNAs, RF PGAs, I/Q downconversion mixers, bandwidth-adjustable low-pass filters, baseband VGAs, a VCO, and a fractional-N PLL. 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.

The ADMTV102 supports dual-band mobile TV standards with low power consumption, such as 200 mW for DVB-H. Using a small, Pb-free, 5 mm × 5 mm 32-lead LFCSP, it is an ideal solution for highly integrated dual-band mobile and portable applications where low power consumption is critical. The part has an I2C® serial bus interface. Applications for the ADMTV102 include DVB-H, DVB-T, DTMB, and CMMB.
