MAX2172 Direct-Conversion to Low-IF Tuner for Digital Audio Broadcast High-Performance Digital Radio Tuner Incorporates Fast and Accurate RSSI Function OVERVIEW The MAX2172 direct-conversion to low-IF tuner is designed for digital audio broadcast DAB and terrestrial digital multimedia broadcast TDMB 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 directconversion 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. MAX2172 Functional Diagram 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.
