The SAB3035 provides closed-loop digital tuning of TV receivers, with or without a.f.c., as required. It also controls up to 8 analog functions, 4 general purpose I/O ports, and 4 high-current outputs for tuner band selection. The IC is used in conjunction with a microcomputer from the MAB8400 family and is controlled via a two-wire, bidirectional I2C bus.
