MAX2172 Direct-Conversion to L
max2172 direct-conversion to low-if tuner for digital audio broadcast
the max2172 direct-conversion to low-if tuner is designed for digital audio broadcast (dab) and terrestrial digital multimedia broadcast (t-dmb) applications, covering an input frequency range of 168mhz to 240mhz (vhf-iii), 1452mhz to 1492mhz (l-band), and also 87mhz to 108mhz (fm). the max2172 achieves a high level of component integration, allowing lowpower, tuner-on-board designs. the direct-conversion to low-if architecture eliminates the need for an if-saw filter while providing a balanced 2.048mhz center frequency baseband output to the demodulator.
the max2172 provides a buffered reference clock at the crystal frequency.
a sigma-delta fractional-n synthesizer is incorporated to optimize both close-in and wideband phase noise performances for ofdm applications where sensitivity to both 1khz phase noise and wideband phase noise related to strong adjacents can be a problem.
the max2172 is available in a 40-pin thin qfn package (6mm x 6mm) with an exposed pad. electrical performance is guaranteed over the extended -40°c to +85°c temperature range.
