Dual Tuner IC is intended for automotive TV applications.

Press Release Summary:




Supplied in 7 x 7 mm TQFN package, MAX2135 receives signals in VHF-low, VHF-high, and UHF bands and integrates 2 signal paths that operate from one fractional-N synthesizer. Each path's output consists of 4 MHz, low-IF signal that interfaces to most demodulator ICs, and on-chip lowpass filters that accommodate 4, 6, 7, and 8 MHz signal bandwidths make device suited for receiving ISDB-T and DVB-T broadcasts. UHF noise figure is 3.8 dB typ, and power consumption ranges from 330-200 mW.

Diversity Tuner for Automotive TV Applications Provides Two Tuners in a 7mm x 7mm Package



Dual-tuner IC provides reception diversity in automotive TV applications.

SUNNYVALE, CA-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX2135 diversity tuner for ISDB-T and DVB-T automotive applications. This device integrates two high-performance signal paths that operate from a single fractional-N synthesizer. Packaged in a small, 7mm x 7mm TQFN, the MAX2135 provides a compact solution compared to designs that use two separate tuner ICs. Additionally, 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.

A versatile device, 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.

The MAX2135 is available in a small, 7mm x 7mm, 56-pin TQFN package, and is fully specified over the -40°C to +85°C extended temperature range. Pricing starts at $8.00 (1000-up, FOB USA). An evaluation kit is available to speed designs.
