ADMTV102 is a RF tuner IC for DVB-H, DVB-T, DTMB and CMMB. It is a single-chip synthesized tuner designed for dual-band mobile TV applications. ADMTV102 features a zero-IF single-conversion architecture that eliminates the need for SAW filters. It covers the entire UHF Band IV/Band V (470 MHz to 862 MHz). Typical AGC dynamic range is -102 dBm to 0 dBm. Low power consumption is 200 mW (UHF). ADMTV102 features a fast switching fractional-N PLL, low phase noise and wide frequency range VCO, bandwidth-adjustable low-pass filter, integrated baseband VGA for direct connection to digital demodulators, noise/linearity optimization through internal RF AGC loop, adjustable take-over point, I2C serial bus interface, small 5 mm × 5 mm, 32-lead lead frame chip scale package (LFCSP) and minimal external components.
The ADMTV102 is a highly integrated CMOS tuner IC designed for mobile TV standards such as DVB‑H, DVB‑T, DTMB, and CMMB. It features a zero‑IF single‑conversion architecture, on‑chip fractional‑N PLL, low‑phase‑noise VCO, and an integrated baseband VGA for direct connection to digital demodulators.
The device covers the entire UHF Band IV/V (470 MHz to 862 MHz), consumes only 200 mW in UHF operation, and is offered in a compact 5 mm × 5 mm 32‑lead LFCSP package. A PC serial bus interface provides simple control, making the ADMTV102 suitable for highly integrated dual‑band mobile and portable TV receivers.
