The new MAX2170/ MAX2171 RF tuners from Maxim are designed for triple-band, dual-mode mobile TV and digital radio. The devices receive VHF band-III and L-band broadcasts, as well as FM. Each device is designed to receive digital audio broadcast (DAB) and terrestrial digital multimedia broadcast (T-DMB) with a minimum of external components. The low-noise, L-band front-end (3 dB noise figure) eliminates the need for an external low-noise amplifier circuit, reducing both cost and size. When tuning VHF frequencies, the on-chip tracking filter rejects out-of-band interference. This tracking filter also doubles as an FM band-select filter.
The devices operate from a 2,7 V to 3,3 V supply and typically draw 150 mW in L-band low-power mode. They contain all necessary blocks to implement a low-IF TV/radio tuner, except a crystal and the (optional) L-band filtering required by some applications. The devices achieve a sensitivity of -101 dBm at L-band, -99 dBm at VHF, and -109 dBm at FM.
Both the MAX2170 and MAX2171 operate off a 24,576 MHz crystal over the -40°C to +85°C temperature range and are available in 6 mm x 6 mm, 40-pin QFN packages. The only difference between the MAX2170 and MAX2171 is the R-divider ratio of the frequency synthesizer. The MAX2170 has a fixed divide-by-1 ratio, while the MAX2171 R-divider value is 3.
