Direct PLL Frequency Synthesizers for Electronic Tuning
•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)
