LC72121MA:PLL Frequency Synthesizers for Electronic Tuning

The LC72121MA are high input sensitivity (20mVrms at 130MHz) PLL frequency synthesizers for 3V systems. These ICs are serial data (CCB) compatible with the LC72131K/KMA, and feature the improved input sensitivity and lower spurious radiation (provided by a redesigned ground system) required in high-performance AM/FM tuners.

技术特性
  • High-speed programmable divider
    FMIN: 10 to 160MHz (Pulse swallower technique (With built-in divide-by-2 prescaler))
    AMIN: 2 to 40MHz (Pulse swallower technique)
    0.5 to 10MHz (Direct division technique)
  • IF counter
    IFIN: 0.4 to 15MHz (For AM and FM IF counting)
  • Reference frequency :
    One of 12 reference frequencies can be selected (using a 4.5 or 7.2MHz crystal element)
    1, 3, 5, 9, 10, 3.125, 6.25, 12.5, 15, 25, 50, and 100kHz
  • Phase comparator :
    Supports dead zone control.
    Built-in unlocked state detection circuit
    Built-in deadlock clear circuit
    An MOS transistor for an active low-pass filter is built in
  • I/O ports :
    Output-only ports: 4 pins
    I/O ports: 2 pins
    Supports the output of a clock time base signal.
  • Serial data I/O :
    Support CCB format communication with the system controller.
  • Operating ranges
