MAX2172ETL/V+T - Maxim Integrated Function Overview

The MAX2172ETL/V+T is a direct-conversion to low-IF tuner for digital audio broadcast in 40 pin TQFN package. 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 low power, 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 centre frequency baseband output to 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 adjacent can be a problem.
Supply voltage range is 2.7V to 3.5V
Operating temperature range from -40°C to 85°C
ACPR (N±1) is +45dBc
Typical Noise Figure for VHF-III is 2.9dB and Typical Noise Figure for L-Band is 3.1dB
VHF-III sensitivity of -101dBm and L-band sensitivity of -101dBm
Baseband overload detector controls RF AGC
Fast channel scan RSSI 5-Bit Output
FM (S+N)/N = 26dB at -111dBm
