SAB3035

The SAB3035 provides closed-loop digital tuning of TV recivers ,with or without a.f.c.,as required.It also controls up to 8 analoge functions,4 general purpose I/O port and 4 high-current outputs for tuner band selection.

Features of the SAB3035 are:(1)combined analogue and digital circuitry minimizes the number of additional interfacing components required;(2)frequency measurement with resolution of 50 kHz;(3)selectable prescaler divisor of 64 or 256;(4)32 V tuning voltage amplifier;(5)4 high-current outputs for direct band selection;(6)8 atatic digital to analogue connverters for control of analogue function;(7)four general purpose input/output ports;(8)tuning with control of speed and direction;(9)tuning with or without a.f.c.;(10)single-pin,4 MHz on-chip oscillator;(11)I2C bus slave transceiver.
