MAX2135A ISDB-T/DVB-T Diversity Tuner Industry's Only Diversity Tuner for Automotive TV Consumes Only 300mW Request Full Data Sheet Active In Production. But some versions of the family are subject to Last Time Buy. The MAX2135A low-power, 6MHz ISDB-T and 6MHz/7MHz/8MHz DVB-T low-IF diversity tuner directly converts broadcast ISDB-T and DVB-T signals to a low-IF using a broadband I/Q downconverter. The operating frequency range covers the VHF and UHF broadcast TV bands from 90MHz to 862MHz. The MAX2135A integrates LNAs, RF variable-gain amplifiers VGAs , VHF and UHF tracking filters, I/Q downconverting mixers, baseband VGAs, and low-IF filters. The device also includes a fully monolithic VCO and tank circuit as well as a complete frequency synthesizer including an on-chip crystal oscillator and output buffer/divider. The device incorporates a 2-wire serial control interface with multiple read and write addresses. A low-power standby mode is available whereupon the signal path is shut down while leaving the serial control interface and register circuits active. Additionally, the entire device can be shut down by an external pin. The MAX2135A is available in a 56-pin thin QFN package 7mm x 7mm with an exposed paddle. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range.
