Maxim Introduces The MAX2135 Diversity Tuner for ISDB-T and DVB-T Automotive Applications

Packaged in a small, 7mm x 7mm TQFN, the MAX2135 provides a compact solution compared to designs that use two separate tuner ICs. The device features a very low, 3.8dB (typ) UHF noise figure, and it consumes only 330mW when both signal paths are active and 200mW when only one path is active. Uniquely combining a small footprint with low power consumption and low noise, the MAX2135 is ideal for automotive in-dash navigation and entertainment systems. The MAX2135 receives signals in three bands: VHF-low (VHF-L), VHF-high (VHF-H), and UHF. Furthermore, on-chip lowpass filters accommodate 4, 6, 7, and 8MHz signal bandwidths, making the device ideal for receiving Japan’s ISDB-T and Europe’s DVB-T broadcasts. The output of each signal path is a 4MHz, low-IF signal that interfaces to most demodulator ICs. Additional features that reduce the external BOM price include on-chip tracking filters, a reference oscillator, and LNAs…
