ADMTV803:  VHF/UHF Tuner IC for Multi-Standard Digital TV

The ADMTV803/804 is a highly integrated CMOS zero-IF conversion tuner IC for multi-standard digital TV applications such as CMMB (UHF band), DTMB, DVB-H, DVB-T, DAB, T-DMB, ATSC-M/H and ISDB-T (full-seg, 3-seg and 1-seg). It has dual VHF and UHF RF frequency inputs. The building blocks include LNA, RFPGA, I/Q downconversion mixer, bandwidth adjustable low-pass filter, baseband PGA, fractional-N ...続きを見る

ADMTV803:  VHF/UHF Tuner IC for Multi-Standard Digital TV

製品概要

The ADMTV803/804 is a highly integrated CMOS zero-IF conversion tuner IC for multi-standard digital TV applications such as CMMB (UHF band), DTMB, DVB-H, DVB-T, DAB, T-DMB, ATSC-M/H and ISDB-T (full-seg, 3-seg and 1-seg). It has dual VHF and UHF RF frequency inputs. The building blocks include LNA, RFPGA, I/Q downconversion mixer, bandwidth adjustable low-pass filter, baseband PGA, 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.

The ADMTV803/804 consumes less than 5.5 mA for DVB-H mode at 10 % duty cycle.

Applications

  • CMMB (UHF band) /DTMB/DVB-H/DVB-T/DAB/T-DMB/ATSC-M/H/ ISDB-T (full-seg, 3-seg and 1-seg) mobile and portable TV receivers
  • VHF/UHF mobile and portable TV receivers
