Multiband Tuner for Mobile Multimedia Applications

The MAX2169 multiband tuner is a world standard digital multimedia broadcast receiver designed for digital mobile TV and radio applications, covering the frequency bands of FM, VHF-III, UHF, and L-band. This device supports reception of RF channels from 0.2MHz to 8MHz wide. An integrated RF tracking filter eliminates the need for an external FM and VHF Band III filter, while the direct-conversion architecture does not require an external IF filter.

The MAX2169 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.

The MAX2169 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.
