The MxL683 is a highly integrated, single-chip receiver for ISDB-T digital TV applications. The MxL683 includes an integrated digital tuner, a 13-segment ISDB-T/SBTVD-T demodulator, an embedded CPU, and a serial MPEG Transport Stream (TS) output. This unique combination of features enables manufacturers to develop a range
of highly differentiated set-top box solutions that are both cost-competitive and high performance.

The MxL683’s IC is fully configurable through a programmable I2C interface. The MxL683 downconverts and demodulates the RF input from a 75Ω source, and provides a standard MPEG serial TS output. Gain control, LO generation, and channel filtering are completely integrated on-chip.

Immunity to LTE and WiFi interference is optimized with the MxL683, providing significant margin to industry standards.

The MxL683 has two supply modes of single 3.3V and dual supply. In dual supply mode operation, 3.3V and 1.8V supplies are required. The MxL683 is available in a 7mm x 7mm QFN48 package.
