Direct PLL Frequency Synthesizers for Electronic Tuning Features •The LM7001J and LM7001JM are PLL frequency synthesizer LSIs for tuners, making it possible to make up high-performance AM/FM tuners easily. •These LSIs are software compatible with the LM7000, but do not include an IF calculation circuit. •The FM VCO circuit includes a high-speed programmable divider that can divide directly. •Seven reference frequencies: 1, 5, 9, 10, 25, 50, and 100kHz •Band-switching outputs (3 bits) •Controller clock output (400 kHz) •Clock time base output (8 Hz) •Serial input circuit for data input (using the CE, CL, and DATA pins)
