RF Flip-Chip Tuners For Japan's Digital Broadcasts Introduced

Sunnyvale, CA -- Maxim Integrated Products introduces the MAX2161 and MAX2162 dual-band, dual-mode tuners for Japanese digital broadcasts. The devices receive UHF and VHF band III and support both 1-segment and 3-segment broadcasts using the ISDB-T standard. The MAX2161 features an I2C-compatible interface, while the MAX2162 has a 3-wire interface for IC-to-IC communication. The small size of these devices enables product designers to produce television systems that meet the tiny-footprint and low-height requirements of the Japanese cell-phone-TV market.

The MAX2161/MAX2162 tuners contain all of the blocks needed to implement a low-IF TV tuner, except for a crystal and the front-end filters needed to reject interfering cellular-transmit signals. In mobile-TV mode, the devices achieve a maximum sensitivity of -98dBm with no external filters or amplifiers, and they can withstand adjacent analog-TV interference of greater than 50dBc at a sensitivity of -95dB. This interference rejection reduces both filter complexity and cost. Each device is RF tested during production utilizing Maxim's proprietary technology.

The MAX2161SEWA/MAX2162SEWA tuners operate from a 2.7V to 3.3V supply over the -40 degrees Celsius to +85 degrees Celsius temperature range, and they draw 110mW (typ) in low-power mode. These devices are available in custom 46-pin wafer level packages (WLPs), and 40-pin TQFN-EP versions (MAX2161ETL* and MAX2162ETL*) will be made available in the future.
