Overview

The LC72131K and LC72131KMA are PLL frequency synthesizers for use in tuners in radio/cassette players. They allow high-performance AM/FM tuners to be implemented easily.

  • High speed programmable dividers :
    FMIN: 10 to 160 MHz (pulse swallower (built-in divide-by-two prescaler))
    AMIN: 2 to 40 MHz (pulse swallower)
    0.5 to 10 MHz (direct division)
  • IF counter :
    IFIN: 0.4 to 12 MHz (AM/FM IF counter)
  • Reference frequencies :
    Twelve selectable frequencies (4.5 or 7.2 MHz crystal)
    100, 50, 25, 15, 12.5, 6.25, 3.125, 10, 9, 5, 3, 1kHz
  • Phase comparator :
    Dead zone control
    Unlock detection circuit
    Deadlock clear circuit
    Built-in MOS transistor for forming an active low-pass filter
  • I/O ports :
    Dedicated output ports: 4
    Input or output ports: 2
    Support clock time base output
  • Serial data I/O :
    Support 'computer control bus' format communication with the system controller.
  • Operating ranges :
    Supply voltage : 4.5 to 5.5 V
    Operating temperature : -40 to +85掳C
