LM7001J - Direct PLL Frequency Synthesizers

General Description

No.

Key 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 100 kHz.
  • Band-switching outputs (3 bits).
  • Controller clock out.
